Such issue affects the UX of any extension that needs to accept user input in the popup (as the user might be unable to switch the layout or select test with `Ctrl+Shift+Left/Right Arrow`).

Reproducible. Tested with addon Dormancy.

Don't see this on other Linuxes, so it seems specific to Ubuntu.

It would be useful to see if it happens with the Unity UI disabled.

I'll bet this is a variation of 1292830 or 1451466. Masayuki, could you confirm if this is the same issue?

Yeah, I think so. When I login to Unity, only pressing down Super key (Windows logo key) causes closing XUL panel. When I login to GNOME Flashback (Metacity), the behavior is changed.

However, when I press Super + Space, keyboard layout change window appears and it causes closing XUL panel. At this time, looks like that parent window is not inactivated. If so, we could behave better though.
