PaddingLeft on Horizontal ScrollView truncates the right of the list on Android only

[WillyReyno]

Description

Hello,

I've encountered the following issue on Android only (works perfectly on iOS & web)

Using ScrollView, I created a horizontal scrollable list of items. But when I apply paddingLeft to the ScrollView, the last item of the list is truncated on Android devices.

Steps to reproduce

1. Go to https://snack.expo.dev/@wreyno/awkward-green-waffle
2. Launch on iOS & Web and notice Option 10 is not truncated
3. Launch on Android and see Option 10 is truncated

React Native Version

0.79.4
