regression: VirtualizedList scrolls infinitely on new item

Description

FlatList is behaving unexpectedly on React Native 0.71 for lists with dynamic height items.
I was able to create a repro pointing to React Native versions:

• 0.69.8
• 0.70.13
• 0.71.12
• 0.72.3

The issue starts to happen on 0.71, but it still happens on 0.72.
Bug happens both on Android and iOS.
I was not able to find the commit that introduced this bug.

React Native Version

0.72.3

Steps to reproduce

See the video. The repro is very straightforward and it simulates a FlatList with dynamic height items.
It's all about scrolling until the list struggles to render the elements. (It's still stuck scrolling as I type the report)
I found it easier to scroll to around 800~1000 and tap Add item top, but it can be reproduced by just scrolling.

(I trimmed the video to fit Github, but it was basically scrolling until it reached 1000 rows)

Commencez par le dépôt ReproListScroll lié et reproduisez le comportement décrit dans la vidéo, en comparant React Native 0.70.13 avec 0.71 et 0.72. Le travail est terminé lorsqu’une FlatList contenant des éléments de hauteur dynamique ne défile plus indéfiniment et ne reste plus bloquée après l’ajout d’un élément près du début.
