Summary:
If text is truncated and an inline view appears after the truncation point, the user should not see the inline view. Instead, we have a bug such that the inline view is always visible at the end of the visible text.
This commit fixes this by marking the inline view as hidden if it appears after the truncation point.
This appears to be a regression. React Native used to have logic similar to what this commit is adding: https://github.com/facebook/react-native/blob/1e2a924ba60001c6f0587c7561536f00b2922cbf/Libraries/Text/RCTShadowText.m#L186-L192
**Before fix**
Inline view (blue square) is visible even though it appears after the truncation point:
The full text being rendered was:
```
<Text numberOfLines={1}>
Lorem ipsum dolor sit amet, consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
<View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
</Text>
```
**After fix**
Inline view is properly truncated:
**Test Plan**
Tested that the inline view is hidden if it appears after the truncation point when `numberOfLines` is 1 and 2. Similarly, verified that the inline view is visible if it appears before the truncation point.

Summary:
I noticed that the _onBlur method was not exactly similar to the _onFocus one in the TextInput component.
After digging, I found that the blurTextInput method in the TextInputState.js file was call twice in a raw instead of once when the textinput component should blur.
By removing this line, I fix this unecessary multiple call.

Summary:
Changing the the this.props.visible if to be ` if (!!this.props.visible === false)` . So passing undefined, or other values wont set the modal to be visible. Granting that anything that is not true, will set the modal to null on the render.
I make this this PR, because on the company that im working, we used a lot of RN. At the moment, we arent using anything like flow or TS. But to grant that the modals will only show if they are set visible to true i have changed the if made.

This results in buttons that were disabled (AccessibilityTraits & NotEnabled === true) never being enabled.
Fix the issue by making the split accessors properly mask in the bits, allowing you unset them without disturbing bits managed by the other accessor.
NOTE: setting AccessibilityTraits and AccessibilityRole or AccessibilityStates will still result in bugs.

Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.
This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.
Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.
https://imgur.com/a/cnL47Z0
More performance gains can potentially be had by increasing the size limit of RCTImageCache: https://github.com/facebook/react-native/blob/1a6666a116fd8b9e8637956de2b41a1c315dd470/Libraries/Image/RCTImageCache.m#L39 but this comes at the tradeoff of being more likely to run into OOM crashes.

Summary:
If a view inside of an inline view became dirty (e.g. its top/left prop changed), its position would not update on screen. This is because Yoga didn't know the view needed to be relaid out because Yoga's dirty signal didn't propagate all the way up to the root.
The problem is that inline views don't have a parent in the Yoga tree causing Yoga's dirtiness signal propagation to get cut off early. The fix is, when an inline views gets dirty, mark the parent Text's Yoga node as dirty. This will cause Yoga's dirtiness signal to propagate all the way up to the root node.
Yoga has a hook to inform you when your node is marked as dirty: `YGNodeSetDirtiedFunc`. We leverage this to find out when an inline view's Yoga node gets dirtied.
React Native almost handled this case. Everything worked fine as long as the inline view was nested inside of a virtual text node like this:
```
<Text>
<Text>
<InlineView />
</Text>
</Text>
```
However, the bug repros when the inline view is nested in a non-virtual text node:
```
<Text>
<InlineView />
</Text>
```
The fix is to move the special dirtiness propagation logic from `RCTVirtualTextShadowView` to `RCTBaseTextShadowView`.
**Test Plan**
Created an inline view. Tested the following kinds of updates on the inline view's content:
- Moved the content
- Removed the content
- Added the content
Tested this for an inline view that is directly inside of a text node as well as one that is nested under a virtual text node.
Here's the code I used for the inline view that moved its content after 2 seconds:
```
const RN = require('react-native');
const React = require('react');
export default class InlineView extends React.Component {
constructor(props, context) {
super(props, context);
this.state = { posBottom: false };
}
componentDidMount() {
super.componentDidMount && super.componentDidMount();
setTimeout(() => { this.setState({ posBottom: true }); }, 2000);
}
render() {
const pos = this.state.posBottom ? 25 : 0;
const color = this.state.posBottom ? 'pink' : 'green';
return (
<RN.View style={{ width: 50, height: 50, backgroundColor: 'steelblue'}}>
<RN.View style={{ width: 25, height: 25, top: pos, left: pos, backgroundColor: color }} />
</RN.View>
);
}
}
```

Summary:
This diff fixes an issue that caused the problem with `regeneratorRuntime` last Friday (more info: https://fb.facebook.com/groups/frontendsupport/permalink/2427883350560427/).
The root issue is that both `InitializeCore` and `FBInitializeCore` are included in the same bundle, this fix just prevents the bundle from being invalid once this happens..
*copied from: https://our.intern.facebook.com/intern/diff/D10444264/?transaction_id=595485237532887*
The way that `regeneratorRuntime` is polyfilled is not correct:
```
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
```
Since a `require`d module is only evaluated once (no matter how many times it's required), defining (and calling) a getter for `global.regeneratorRuntime` twice will end up storing `undefined` to `global.regeneratorRuntime`.
There were no issues before this diff because the ordering of requires made things work by coincidence, e.g the following code will work:
```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Set up regenerator for the second time. This will just override the previous getter (which has not even got executed so
// the `regenerator-runtime/runtime` module has not been evaluated yet.
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Now access regenerator
global.regeneratorRuntime;
```
But the following code won't work:
```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Access regenerator. This will cause the previous getter to be called, and the `regenerator-runtime/runtime` module will get evaluated.
// Here, `global.regeneratorRuntime` will have a correct value.
global.regeneratorRuntime;
// Set up regenerator for the second time. This will define a new getter for `global.regeneratorRuntime`, which will delete `delete global.regeneratorRuntime`
// and return undefined (note that `require('regenerator-runtime/runtime');` is a noop since the module has been already evaluated).
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
```

Summary:
1. The user inserts a character ('0') at index 0. Because the range matches 0, 0, predictedText is set to that character that was inserted.
2. In textInputDidChange, it discovers a mismatch between the rendered text ('1234') and predicted text ('0')
3. This triggers textInputShouldChangeTextInRange to be called again with the 'new' text that it thinks was just added ('1234')
4. It goes to insert this text, but runs into the maxLength limit, so it gets truncated and then inserted.
(I'm not totally sure why only happens if maxLength is set - I need to look into that.)
One fix for this is to just get rid of the range check, but that'll regress #18374. I decided to just check and see if the rendered text is empty instead of checking the range where text could be inserted, since that seems like it should properly handle both cases.

Summary:
This fixes#19193
Characters of different languages may have different height and different baseline, even with a same font and same font-size. When they mixed together, iOS will adjust their baselines automatically, to display a suitable view of text.
The problem is the behavior of dealing with the text-style property 'lineHeight'.
It once to be a right way at version 0.52.3, to setting a base-line-offset attribute for the whole range of the string. However, in current version, it enumerated the string, and set a different base-line-offset for different font-height characters.
And this behavior broke the baseline adjustment made by the iOS. It just make every character's baseline aligned to a same line. But it is not supposed to displaying characters of different languages like that. Chinese characters' baseline is the bottom of each, however, it is not for English characters.
So maybe it is the better way to give a same value of base-line-offset attribute for the whole string. And this PR just did that: found the biggest value of font-height in the text, and calculate the offset with that biggest value, then set to the whole string. This will keep the origin baseline adjustment for different languages' chars made by iOS.
Since I always got an error when running the snapshot test locally, I can't even pass the them with the unmodified code in master branch.
The error is "Nesting of \<View\> within \<Text\> is not currently supported."
After I comment all of the check of that error from the source code, I got a different snapshot from the reference ones. It seems that all components which will cause that error are not rendered in the reference images.
Since this PR changed the behavior of 'lineHeight' property, it's better to add a new snapshot case for the situation of different-language-characters' mixture. So maybe somebody could help me with that or maybe it should be a issue?
