gnome-shell crashed with assertion failure window.c:1552:meta_window_unmanage: assertion failed: (window->display->focus_window != window)

[Rui Mesquita]

[ Impact ]

The gnome user interface hung for a minute or so, after pressing 'x' to close a terminal window

[ Test case ]

- Run wine on wayland (natively)
- Open a window containing a dialog box
- Close the dialog

Otherwise

- Closing a terminal should work

[ Regression potential ]

Windows are wrongly focused on click.
