This problem came up with MAUI's Frame class, as FrameRenderer is not an NSObject but somehow produced a cycle that I could cause problems with at runtime.

Examples:

• [ios] fix memory leak in Frame, VisualElementRenderer dotnet/maui#18552
• [ios] fix memory leak in ImageButton dotnet/maui#18602
• [ios] fix memory leak in Stepper dotnet/maui#18663
• [ios] fix memory leak in Slider dotnet/maui#18681
