starting a wl app from another tty breaks maximise/drag
Launching a wayland application from another tty, then going to mutter's tty to see it there used to work. E.g. I start mutter in a random tty with
mutter --wayland, then go back to full GNOME and run
WAYLAND_DISPLAY=wayland-1 /usr/lib/weston/weston-terminal, and when going back to mutter's tty weston-terminal would be there and it would work fine. But since this commit, in this scenario, when going back to mutter's tty, weston-terminal appears, but you can't drag it and maximising it is broken.
