[Mac/iOS] StackLayout fails to render content while applying Clip, and the layout is placed inside a Border with Background in .NET MAUI

[VishalOmprasad]

Description

When applying a RoundRectangleGeometry clip to a custom StackLayout placed inside a Border, the layout fails to render correctly in Mac and iOS platforms. The issue occurs only when the parent Border has a Background set. Removing the Background property results in normal rendering.

Steps to Reproduce

1. Download and open the attached .NET MAUI project in the public repository.
2. Build and run the .NET MAUI app in iOS/Mac
3. Observe the CustomView inside the Border.
