FlatList scrollToEnd ignores contentContainerStyle bottom padding

If you have a <FlatList /> (and possibly other scrolling views) with a contentContainerStyle of {paddingBottom: 200}, when scrollToEnd is called it scrolls to the bottom of the content, not to the bottom of the entire FlatList. So if you already scrolled to the very end (including padding), the FlatList will actually scroll back up to the bottom of the last item in the list.

Steps To Reproduce

See https://github.com/mjmasn/FlatListScrollIssue

1. Run the app on android
2. When the app loads, scroll to the very bottom of the flat list so you can see the 200px bottom padding
3. Now whenever scrollToEnd is called, the FlatList will scroll back up, ignoring the padding.

Describe what you expected to happen:

FlatList scrolls fully to the bottom, including the padding height.

when you write not stale, I and others receive notification, we un-subscribe and the issue becomes stale

🤷‍♂️ What can I say, my good friend stale bot disagrees with you…

stale bot removed the Stale label yesterday

But in all seriousness this is still a valid issue so it needs to be kept open. The RN maintainers can decide what to do with it next time they do a triage. It’s probably a good first issue if someone wants to contribute.

I’m not in a rush to write a PR because I have other commitments and in most cases there’s an easy workaround.
