maintainVisibleContentPosition fails with rapid FlatList data updates

[khushal87]

Description

maintainVisibleContentPosition does not maintain scroll position when items are added rapidly to the beginning of FlatList data (intervals < 200ms), causing scroll jumps and poor UX in chat applications.

Steps to reproduce

1. Use the provided reproduction code
2. Scroll to the bottom of the list
3. Start rapid updates (80ms interval)
4. Observe scroll position jumping despite autoscrollToTopThreshold being passed 10. This doesn't happen when messages are sent slowly >500ms.
