Simple script to reproduce duplicate event delivery

If a widget has both the focus and has the input grabbed then unhandeld events will be delivered twice. This happens both on Wayland and X11 (using Xwayland).

See attached small python script as a test case. After 5 seconds a grab will be added and then each key press is printed twice.

I think that this must have changed not long ago as I had not seen the duplicate events earlier.
