Children inherit parent's properties when parent has boxShadow + scale + overflow:hidden

Description

When a parent View has all three of these properties:

• boxShadow
• transform: [{ scale }] ← Required to trigger the bug
• overflow: 'hidden'

Children incorrectly inherit the parent's borderRadius and scale transform(and others properties if set), even though these properties should not be inherited.

Additional Context

Removing any one of these properties makes the bug disappear

• Removing overflow: 'hidden' makes the bug disappear
• Removing boxShadow makes the bug disappear
• Removing transform: scale makes the bug disappear

Everything works great on Android

Steps to reproduce

1. Create a parent View with these exact properties:
   overflow: 'hidden'
boxShadow: ...
transform: [{ scale: ... }]
2. Create a child View inside the parent with:
   borderRadius: 0 (should be square)
3. Run the app on iOS/tvOS

Commencez par exécuter le reproducer Snack obligatoire sur iOS ou tvOS, puis comparez sa sortie avec Android en faisant varier boxShadow, scale et overflow:hidden. Aucun fichier source ni test n’est nommé dans l’issue. Le travail est considéré comme terminé lorsque la View enfant n’hérite plus de borderRadius ou de scale du parent avec la combinaison signalée, sans régression sur les autres plateformes.
