Button does not accept clicks on its entire size

[CodeDevAM]

Describe the bug

When a button has a big horizontal extend it has a relatively large area on the left and on the right where a click does not get accepted.

On mouse down the button shrinks and it seems to only accept clicks on mouse release on the shrinked button size.

This is because Fluent theme shrinks the Button while pressed and Button requires the pointer to be within its bounds upon release for a click event to occur.

The easiest way is to replace the shrinking behavior below via styling:

See https://github.com/AvaloniaUI/Avalonia/discussions/16100 for details.

Thanks for the advise.

However I would consider this as an unexpected behaviour. In my opinion the click logic of a button should work on the original size of the button when the mouse is pressed down. Because otherwise the UI do feel unresposive when you hit the button at the wrong place.
