Description
Description
When you have a list of <Pressable> inside a <FlatList>, and the list is short enough to fully fit on the screen (so that no scrolling is actually needed), then if you do scroll the list a whole bunch of onPress events will fire on the Pressable list items.
The expected behavior is that onPress should only be triggered when actually pressing an item.
I initially filed this report on the FlashList repo, but after further testing I actually believe this is a React Native issue.
Here's the FlashList issue: https://github.com/Shopify/flash-list/issues/1461
Here's an older very similar React Native issue that's been closed without a fix: https://github.com/facebook/react-native/issues/27355

Research direction
Start by running the linked Expo/Bun FlashList reproducer on Android with React Native 0.76.5 and confirm the Pressable/FlatList behavior described here. Trace the relevant React Native behavior from that reproduction; done means scrolling a short FlatList no longer fires onPress, while an actual press still does.
