[v3] Regression: FlatList content doesn't scroll when stickyHeaderIndices is set, does not affect LegacyFlatlist #4328

Description

I updated react-native-gesture-handler from version 2.32.0 to 3.1.0 and noticed that some Flatlists in my app stopped scrolling, both in Android and iOS. The issue seems to be related to the property stickyHeaderIndices. LegacyFlatlists do not suffer from this issue, so this appears to be either a regression in the new implementation or a migration step that isn't documented or that I may have overlooked.

Steps to reproduce

1. Download the flatlist-no-scroll branch from the example repo
2. Run the app in either IOS or Android
3. Scroll both lists provided in the example
4. You will notice the Flatlist scroll indicator will update but not the content of the list, LegacyFlatlist should work as expected.
