Description of problem:
When I have one window of firefox flashing, and many windows open so firefox
bunches into a single group, the group flashes in the taskbar (which is good). 
However when you click on the group, it isn't clear which window in the pop-up
is the flashing window, so you need to go through all of them manually to find it.

Solution:
There should be some kind of visible indication of which window is the flashing
window when you click on the group in the taskbar.  Maybe that one window title
in the pop-up menu should be flashing too?  Seems most logical.

Version-Release number of selected component (if applicable):
libwnck-2.10.0-3
