Description

On iOS and MacCatalyst, if you set the BackgroundColor of a SearchBar to Transparent, the background goes black. This only seems to occur if you change it or set it explicitly and not with the default value.

Does not occur on Windows or Android.

Steps to Reproduce

1. Create a new .NET MAUI app
2. Add a SearchBar
3. Explicitly set the BackgroundColor property of the SearchBar to Transparent, or change it to Transparent at runtime
4. Observe the black background
