gnome-shell/js/ui/windowManager.js
Dan Winship 4117739abb Don't do window transitions while the overlay is active. Part of #568983.
Previously we were only doing this check for switch-workspace, but it
makes sense to do it for all transitions, since they won't be visible
anyway, and they might interfere with the overlay's operations by moving
windows around unexpectedly.
