Reproduce the issue using the attached DemoLayout sample, starting with NativeViewClass and its TouchesBegan, PressesBegan, PressesEnded, and PressesCancelled overrides. Trace how the custom handler is registered in MauiProgram and connected through LayoutHandler to MainPage. Done means pressing Space once produces one PressesBegan event with populated key information on Mac Catalyst.
