Separator not being rendered

[diegolmello]

Description

There are a few issues about this topic, but none of them have a solution:

• https://github.com/facebook/react-native/issues/28575
• https://github.com/facebook/react-native/issues/22927
• https://github.com/facebook/react-native/issues/13959

I've attached a simple FlatList snack showing the separator isn't rendering sometimes. It can be reproduced both on iOS and Android. The easier way to do it is to decrease display size on a11y, but it can be reproduced on default as well.

React Native Version

0.71.4

Output of npx react-native info

Expo 47 from snack.

Steps to reproduce

Add a separator to a FlatList with hairlineWidth or 1.

Snack, code example, screenshot, or link to a repository

Note missing separators on 2-3, 7-8, etc

Still a problem on Android (we are on 0.70.4).

Have temporarily set everything 1dp for Android platform.

Going to try an updated version of this old PR that never got merged as a patch later
