Bug 530059: [Wayland] Show In menu appears in the wrong place

Events used to spawn menus can contain inaccurate window information on
Wayland. If we are running on Wayland, set the event window to be that
of the mouse pointer location.

Tested on GTK3.22 using the Wayland backend. X11 is unaffected by this
fix. No AllNonBrowser JUnit tests fail.
