Status: RESOLVED INVALID

(Firefox :: Keyboard Navigation, defect)

With a DHTML menu, a sublist of links is set to display:none. When the user tabs to the sublist's name in the upper list, the sublist is set to display:block. But whereas in Firefox 2, the links in the sublist are then in the taborder, in the current Minefield it is impossible to tab to the links in the sublist. See attached testcase for an example. Unless I'm mistaken, this is a serious accessibility regression.

Reproducible: Always

Steps to Reproduce:
1. Open the testcase.
2. Tab with the keyboard to A-Z.
3. Try to tab to the first link in the sublist ("Skip A-Z").
Actual Results:  
Cannot tab to "Skip A-Z".

Expected Results:  
Can tab to "Skip A-Z".

Okay, there doesn't seem to be a regression here. The problem was that blur events within the sublist were bubbling up and being caught, triggering hiding of the sublist. So a solution is to cancel that bubbling.
