### Background
On Android view groups can be marked as "transitioning" with a `ViewGroup.startViewTransition` call. This effectively ensures, that in case a view group is marked with this call and its children are removed, they will be still drawn until `endViewTransition` is not called.
This mechanism is implemented in Android by [keeping track of "transitioning" children in auxiliary `mTransitioningViews` array](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/view/ViewGroup.java#7178). Then when such "transitioning" child is removed, [it is removed from children array](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/view/ViewGroup.java#5595) but it's [parent-child relationship is not cleared](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/view/ViewGroup.java#5397) and it is still retained in the auxiliary array.
Having that established we can proceed with problem description.

Explanation (copied from [here](https://github.com/software-mansion/react-native-screens/pull/2495#issuecomment-2478915818)):
I've debugged this for a while now & I have good understanding of what's going on. This bug is caused by our usage of `startViewTransition` and its implications. We use it well, however React does not account for case that some view might be in transition. Error mechanism is as follows:
1. Let's have initially simple stack with two screens: "A, B". This is component rendered under "B":
```javascript
<View //<-- ContainerView (CV)
removeClippedSubviews={false}
style={{ flex: 1, backgroundColor: 'slateblue', overflow: 'hidden' }}>
<View removeClippedSubviews style={{ height: '100%' }}> // <--- IntermediateView (IV)
<View removeClippedSubviews={false} style={{ backgroundColor: 'pink', width: '100%', height: 50 }} /> // <--- ChildView (ChV)
</View>
</View>
```
2. We press the back button.
3. We're on Fabric, therefore subtree of B gets destroyed before B itself is unmounted -> in our commit hook we detect that the screen B will be unmounted & we mark every node under B as transitioning by calling `startViewTransition`.
4. React Mounting stage starts, view hierarchy is disassembled in bottom-up fashion (leafs first).
5. ReactViewGroupManager receives MountItem to detach ChV from IV.
6. A call to [`IV.removeView(ChV)` is made](https://github.com/facebook/react-native/blob/9c11d7ca68c5c62ab7bab9919161d8417e96b28b/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/view/ReactClippingViewManager.kt#L58-L73), which effectively removes ChV from `IV.children`, ***HOWEVER*** it does not clear `ChV.parent`, meaning that after the call, `ChV.parent == IV`. This happens, due to view being marked as in-transition by our call to `startViewTransition`. If the view is not marked as in-transition this parent-child relationship is removed.
7. IV has `removeClippedSubviews` enabled, therefore a [call to `IV.removeViewWithSubviewsClippingEnabled(ChV)` is made](https://github.com/facebook/react-native/blob/9c11d7ca68c5c62ab7bab9919161d8417e96b28b/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/view/ReactClippingViewManager.kt#L68). [This function](https://github.com/facebook/react-native/blob/9c11d7ca68c5c62ab7bab9919161d8417e96b28b/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/view/ReactViewGroup.java#L726-L744) does effectively two things:
1. if the ChV has parent (interpretation: it has not yet been detached from parent), we compute it's index in `IV.children` (Android.ViewGroup's state) and remove it from the array,
2. remove the ChV from `mAllChildren` array (this is state maintained by ReactViewGroup for purposes of implementing the "subview clipping" mechanism".
The crash happens in 7.1, because ChV has been removed from `IV.children` in step 6, but the parent-child relationship has not been broken up there. Under usual circumstances (this is my hypothesis now, yet unconfirmed) 7.1 does not execute, because `ChV.parent` is nulled in step no. 6.
### Rationale for `startViewTransition` usage
Transitions. On Fabric, when some subtree is unmounted, views in the subtree are unmounted in bottom-up order. This leads to uncomfortable situation, where our components (react-native-screens), who want to drive & manage transitions are notified that their children will be removed after the subtrees mounted in screen subviews are already disassembled. **If we start animation in this very moment we will have staggering effect of white flash** [(issue)](https://github.com/software-mansion/react-native-screens/issues/1685) (we animate just the screen with white background without it's children). This was not a problem on Paper, because the order of subtree disassembling was opposite - top-down. While we've managed to workaround this issue on Fabric using `MountingTransactionObserving` protocol on iOS and a commit hook on Android (we can inspect mutations in incoming transaction before it starts being applied) we still need to prevent view hierarchy from being disassembled in the middle of transition (on Paper this has also been less of an issue) - and this is where `startViewTransition` comes in. It allows us to draw views throughout transition after React Native removes them from HostTree model. On iOS we exchange subtree for its snapshot for transition time, however this approach isn't feasible on Android, because [snapshots do not capture shadows](https://stackoverflow.com/questions/42212600/android-screenshot-of-view-with-shadow).
### Possible solutions
[Android does not expose a method to verify whether a view is in transition](https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/view/ViewGroup.java#7162) (it has `package` visibility), therefore we need to retrieve this information with some workaround. I see two posibilities:
* first approach would be to override `startViewTransition` & `endViewTransition` in ReactViewGroup and keep the state on whether the view is transitioning there,
* second possible approach would be as follows: we can check for "transitioning" view by checking whether a view has parent but is not it's parent child (this **should** be reliable),
Having information on whether the view is in transition or not, we can prevent multiple removals of the same view in every call site (currently only in `removeViewAt` if `parent.removeClippingSubviews == true`).
Another option would be to do just as this PR does: having in mind this "transitioning" state we can pass a flag to `removeViewWithSubviewClippingEnabled` and prevent duplicated removal from parent if we already know that this has been requested.
I can also add override of this method:
```java
/*package*/ void removeViewWithSubviewClippingEnabled(View view) {
this.removeViewWithSubviewClippingEnabled(view, false);
}
```
to make this parameter optional.

Changelog: [Internal]
`getModuleInstanceFromClass:` is a delegate method intended to be implemented by the product layer to provide modules. if it is not implemented to return a module for a given key, `RCTTurboModuleManager` will simply call `new` on the TM class.
however, these two paths differentiate - for `getModuleInstanceFromClass:`, we will call `_attachBridgelessAPIsToModule:` which provides objects like surfacePresenter to the native module.
if we fallback to calling `new`, then this attachment does not happen, even if the app has already been migrated to bridgeless modules.
thus, the fix in the case is to lift the fallback into RCTInstance as well, and decorate the APIs onto the new fallback.

I don't think this is the right approach: There could be legitimate reasons to continue executing native -> js calls post first js fatal.
I don't think it does *much*: it doesn't noop native -> js calls executed on the runtime scheduler, which should be most of them.
## Changes
Instead of trying to prevent that fatal, just let it happen. Then, don't report the second fatal: D66193194 and D66392706.
## Safetly
The production impact is negligible: This codepath is executed only after early js errors. There shouldn't be any in production right now.
We've spent a lot of time making our javascript error handling pipeline's coverage compresive. So, after an early js fatal error happens, subsequent js fatals should get handled properly.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48020
Progress towards Performance panel display parity for User Timing events in Chrome DevTools.
- Support nullable `track` name in `ReactPerfLogger`, passing track name directly to `FuseboxTracer`.
- Update `FuseboxTracer` to register "Main" process and send V8-aligned `blink.user_timing`-categorised tracing events.
The previous track naming strategy continues to be used under Perfetto.

**Better, but not perfect yet**
For now, this is probably the upper limit of how aligned we can be with Chrome on web, since our forked DevTools frontend is 6mo+ behind `main`. Notably, it does not include equivalent custom track handling today: https://github.com/ChromeDevTools/devtools-frontend/commit/4b4435feef14c5c0ac71d932940c6ea7613f8afe

> Importing an exact trace from Chrome into RNDT is unable to sub-group the "Timings" track.
