Bug 400910

SUMMARY


STEPS TO REPRODUCE
1. Have a panel
2. Put the default task manager on it
3. Double click somewhere on the panel, on the task manager itself

OBSERVED RESULT
First the "tabs" showed there flicker, secondly the application that is focused maximizes for some reason.

EXPECTED RESULT
No flicker. The maximize is actually quite nice.
