Unity8 can't display multi-window apps (or menus/tooltips).

Fixing bug 1497085 was a great start. However instead of crashing Unity8 now just shows the most recently created window by the app in the apps /single window/, and stretches it too. When such a secondary window like a menu or tooltip closes, you never get back to the original app window. So existing apps still aren't quite usable yet.

Test case:
sudo apt-get install mir-demos
mir_demo_client_multiwin -m /var/run/user/*/mir_socket -- --desktop_file_hint=unity8

Expected: Three windows (red, green, blue)
Observed: Only the blue window

You can also experience the same bug with lots of apps via: Xmir -rootless under Unity8.
