// ...For some reason it creates Microsoft.Maui.Graphics.Rect but it converts it into Android.Graphics.Rect using implicit operator before storing it in ResourceDictionary. When it's about to call SetValue, it tries to convert it back to Microsoft.Maui.Graphics.Rect using unbox.any and I assume that's what fails.
Description
I get an "InvalidCastException" when I have an element inside an AbsoluteLayout with its LayoutBounds bound to a Rect defined in a ResourceDictionary and XamlC is enabled on Android. This only happens on Android, it does not happen on iOS. Here is an extremely simple code example that causes the problem:
It happens in Release configuration, but it also happens in Debug configuration with defaults except with XamlC enabled.
