Description

After upgrading to expo 52 and react-native 0.76.3 I noticed some of my dashed borders had disappeared in some cases on iOS. On further investigation, I discovered that dashed borders no longer work when borderStyle: "dashed" | "dotted" are used in combination with overflow: "hidden" or overflow: "scroll". Instead of a dashed or dotted border, it shows a solid border.
Dotted and dashed borders work correctly with overflow: "visible"
Dotted and dashed borders also work correctly in android.

I took a cursory look through the source code, but couldn't see the issue - that being said, if someone can point me in somewhat the right direction, I'd be happy to take a swing at a fix.

Steps to reproduce
  1. Install the application and launch ios emulator
  2. look at the code in the stylesheet for the two items
  3. look at the missing borderStyle

Línea de trabajo

Comienza con el reproducer de borderIssue enlazado y compara el renderizado en iOS de los bordes discontinuos y punteados con overflow: hidden o scroll frente a visible. Sigue la ruta de renderizado de bordes de React Native para iOS para identificar por qué estos casos se vuelven sólidos. Se considera terminado cuando los bordes discontinuos y punteados se renderizan correctamente con los valores de overflow afectados sin introducir regresiones en Android ni en el comportamiento de overflow visible.
