mutter/src/wayland/meta-wayland-text-input.c
Carlos Garnacho 405ec8edc2 wayland: Forward button press / touch down to Wayland text-input impls 
These are ClutterInputFocus subclasses, so this will trigger reset of
the input method. As the .done event is possibly deferred in the
zwp_text_input_v3 implementation, ensure the changes caused by the
reset are flushed immediately, before the button press is forwarded
to the client by MetaWaylandPointer.
