Root Cause
When using UseMauiCompatibility, the ContentView handler is set to RenderToHandlerShim instead of ContentViewHandler. As a result, the measuring logic is managed by VisualElementRender, leading to a size of 0 being returned.
Description of Change
Registering the ContentView handler with the control as ContentView instead of IContentView will resolve the issue.
