Summary

This PR changes the logic we use to execute animations. It executes all animations on the native thread instead of the UI and native thread to prevent animation synchronization issues. If at least one layout prop animation is detected in the batch, the whole animations batch is executed on the native thread.

It fixes the issue that can be seen only on paper. Fabric works fine as it uses its own logic.

Test plan

  • Open the empty example in the paper example app on android

Remarks

Performance impact must be assessed before merging this PR. It moves the execution of all updated to a single thread, which may not be that efficient compared to running updates on 2 threads (native and UI).

Hi! I've faced crash issues using this patch and react-native-svg.
It looks like this:
