We are using XGrabPointer to get mouse input and dismiss popup menus on mouse click.

Obviously, it does not work when we are trying to mouse click outside of area controlled by XWayland(window's title, desktop, wayland native apss).


 prototype of not perfect workaround

For a first look this workaround seems to work reliably except only one case:

clicking on window's title containing origin component does not lead to focus change, thus we don't hiding popup.
