Can't exclude gnome extension from tilling

[vinismarques]

(1) Issue/Bug Description:
I use the Pano Gnome extension and it does not work on X11 when Tilling is enabled and the mouse cursor is on the "active" display. It only works when tilling is disabled or if I move the cursor to the other display (without clicking) and press the shortcut again.

(2) Steps to reproduce (if you know):
Have the Pano extension installed and enabled, tilling enabled, and using X11. With two monitors, click on one to focus it and keep the mouse there, then press Pano's keyboard shortcut to show the interface.

(3) Expected behavior:
Pano's interface should appear. But it only works when tilling is disabled or when the mouse is hovering over the "inactive" display.
