Per the discussion with beng, this code will need to be adjusted.

Also, what happens to xinput2 handling when inside this case?

I am unsure how it would need to change.
The menu themselves receive do not receive XInput2 events. This is because the
Xwindows for the views-menus aren't created by GTK+, and so we do not set them
up to receive XInput2 events. However, they do still receive XInput events, i.e.
they can still be focused, navigated and clicked on.
