Layout is sometimes broken after data is updated

[Elrohil44]

Current behavior

Sometimes when data is updated and some sections are inserted and/or removed, then the layout breaks. In my case the last item is cut off although the footer is displayed.
Reproduction video

1. At first the content is correctly displayed
2. I press toggle elements to remove two elements from data array
3. The last element is not rendered correctly – it does not fit within render window

Expected behavior

All elements should be fully visible after content changes.

I got the same behavior, if I change the elements in the list, sometime it got disappear. It's random but I find that it happens usually when switching for a long list to shorter one, in the inverse case, from short list to longer list, I cannot produce the bug.

I have the same problem. Each message item has a dynamic height, so I had to revert back to using FlatList. Hopefully, it will be fixed soon.
