IE 11 no longer supports the legacy document.selection API.
Their implementation of window.getSelection() doesn't support
the extend() method, which we were relying on.
If the selection is RTL and selection extend is missing, then just
flip the selection.
Newer versions of WebKit and Blink will support both `document.body.scrollTop` and `document.documentElement.scrollTop`. Therefore, implementing cross-browser compatibility by summing the two will no longer work.
This changes React to use `getUnboundedScrollPosition` so we get the fix and consistency in one change!

When a ReactDOMComponent is created with the property `disabled: true` subsequently setting the property to `disabled: false` the HTML attribute `disabled="true"` was being left in the DOM.
If we are to unmount a component mounted into a document element we should
unmount it from document.documentElement and not from document.firstChild which
is a doctype element in this specific case.
Fixes#447.
We do this by moving the actual anchored element up in the page without moving the actual text. (Apple uses a similar trick in their framed docs.) Now this looks a bit sillier on smaller screens but it's better overall.
Currently, default props as defined by `getDefaultProps` are only used if a prop is not specified (using `X in Y` check).
However, this makes it difficult for composing components to pass along the state of not being defined, for example:
render: function() {
// If `this.props.someProp` is not set, `InnerThing` should use the default value.
return <InnerThing someProp={this.props.someProp} />;
}
This changes the requirement for falling back to the default value to an undefined check (using `typeof X === 'undefined'`).
Remember that one time I wrote release notes and said:
> This is a breaking change - if you were using class, you must change
> this to className or your components will be visually broken.
Good thing I didn't listen to myself!
We had something that did the same sort of protection. The module
differs slightly (returns document.body instead of undefined) but
looking at the callers, that should be ok.
