Desktop switcher does not hide when keybindings are changed from Ctrl+Alt+Arrow to Meta+[hjkl]

[Kai Groner]

Background:
These key bindings worked fine in 12.04beta1 from March 2nd until I updated on March 13th. Before March 2nd I was using gnome-shell, without compiz.

Steps:
1. Run unity --reset --replace
2. In keyboard control panel (or in the CCSM Desktop Wall page), change bindings for "move to desktop {left,right,up,down}" from Ctrl+Alt+{Left,Right,Up,Down} to Meta+{h,l,k,j}.
3. After switching desktops using the new keybindings, observe that the switcher stays open until I press Escape or I press and release Ctrl+Alt.

Other thoughts:
- I didn't have this problem last time I used Gnome 2 with compiz (about a year ago).
- Meta+{Left,Right,Up,Down} have other bindings so I avoided testing these, I just tested Meta+Up and had the same problem.
