Android: borderStyle: 'dotted' | 'dashed' breaks when backgroundColor has opacity (Expo SDK 54)

Description

When using borderStyle: 'dotted' or borderStyle: 'dashed' on a View, the border renders correctly only if the background color is fully opaque.

If the View has a borderColor with opacity (e.g. rgba(...) or a color with alpha), the border style does not render correctly (or is not applied at all).

This issue happens only on Android and seems to be a regression introduced in Expo SDK 54.
The same code works correctly in Expo SDK 53.

Steps to reproduce

1. Create a View
2. Apply:

• borderWidth
• borderStyle: 'dotted' or borderStyle: 'dashed'

3. Set a backgroundColor with opacity (e.g. rgba(0,0,0,0.1))
4. Run on Android

Commencez par exécuter le Snack obligatoire sur Android avec React Native 0.81.4 et Expo SDK 54, puis comparez le même comportement de borderStyle et de l’arrière-plan translucide dans SDK 53. Suivez le chemin de rendu Android pour les bordures en pointillés et en tirets de View ; c’est terminé lorsque les deux styles sont correctement rendus lorsque backgroundColor utilise rgba ou alpha.
