```
AB Merge
UI thread -----------*----------*------------
JS thread ---*------------*------------------
React abFlush
```
In this scenario:
- AB - Animation Backend update
- React - React commit
- Merge - Merge commit
- abFlush - Animation Backend [flush](https://www.internalfb.com/code/fbsource/[aecb908843884d2fe57e866611a468e47b36518b]/xplat/js/react-native-github/packages/react-native/ReactCommon/react/renderer/animationbackend/AnimationBackend.cpp?lines=242-268)
1. React revision captures the currently mounted main revision and applies the update on top of it. The result becomes the new `reactRevision`.
2. Animation Backend performs updates on the mounted tree, and requests a flush
3. The flush runs on the JS thread, clearing the `animatedPropsRegistry`
4. Merge commit runs, mounting the `reactRevision` and effectively dropping the updates.
This diff changes the flush to happen on the react revision instead, preventing this from happening.
