(Android 9) Flatlist header shows up underneath items if items have elevation: 1 or higher; can't be fixed with zindex.

[0xIrakli]

Description

Flatlist ListHeaderComponent together with stickyHeaderIndices={[0]} shows up under items when scrolling, if items have elevation 1 or higher. Seems to only show up on my older device (Android 9), I've tried to fix this with both zIndex and elevation on the header component (also with ListHeaderComponentStyle) but nothing changes.

Steps to reproduce

1. open the provided snack with an older device (Android 9), I can't test Android 10 at the moment but when using Android 11 or higher the issue doesn't show up.
2. scroll the FlatList
3. observe header component
