WE'VE SWITCHED TO DRAFT.JS, SO THIS REPO IS NO LONGER MAINTAINED!
Last version was released 8 months ago && was just a beta, not production ready.
If selection is inside a block of text that's removed, the part of the
selection that's inside the bounds should clamp to the offset of the
removed text. So if your cursor is at offset 5, and you're deleting
from 2-10, your cursor should end up at offset 2.
* Fix iOS autocorrect issues with Backspace and Return
Handling Backspace and Return keystrokes in `onNativeBeforeInput`
ensures that iOS recognizes word and paragraph breaks and generates
appropriate autocorrect suggestions.
Fixes#1471

Propose to flush change immediately instead of delaying it using `setTimeout()`.
- Flushing change is only use for `props.onChange()` callback and invoked at the end of render lifecycle (didMount/didUpdate), can't find the rationale for delaying it.
- `setTimeout()` delay are not dependable for a predictive behaviour
- `onChange()` is an important callback for a controlled component, delaying it can cause race condition. e.g. any changes outside of the component lifecycle that happen between the delay of flushing change will be overridden
```
<IFrameComponent>
<SlateEditor {...props} />
</IFrameComponent>
```
Since react unmounts from top down, `IFrameComponent` will unmount first (destroying its window), then `SlateEditor` will unmount and attempt to access the iframe window (which no longer exists) throwing `Uncaught TypeError: Cannot read property 'document' of undefined`.
It should be safe to skip removing event listeners from windows that no longer exist since they will be garbage collected upon destruction of the window anyway
* Remove `value` from `operation.fromJSON`
Value is only used for local undo / redo, so it shouldn't be
serialized along with the rest of the data.
* Continue to parse a specified `value` into an Operation
* fix(at-range): forward deletion now stays with next block.
* fix(at-range): use select instead of moveToRangeOf
