944716 - Tooltips of context menuitems overlapping another menu don't appear, causes highlight failure on menuitems

Status: UNCONFIRMED

(Core :: XUL, defect)

Attachment: Test add-on

User Agent: Mozilla/5.0 (Windows NT 6.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36

Steps to reproduce:

I made an extension that adds a new toolbar with one menu button, associated a context menu for each menuitem of that menu, and added a tooltip to each menuitem of the context menu.
1) Click on toolbar button, menu appears.
2) Right click on a menuitem, context menu appears.
3) Mouse over the part of the context menu which overlaps with the main menu


Actual results:

The context menuitem which was moused over doesn't highlight correctly (highlights for a moment then disappears) and its tooltip doesn't appear at all.

The problem only occurs where the context menu overlaps with the main menu. I.e., if I mouse over the part of the context menu which does not overlap with the main menu, everything works fine. Also, the highlighting problem goes away when I get rid of the tooltiptext attributes.

Did it use to work with previous versions of Firefox?

I tested with Firefox 17 (to see if a regression was possible) and the add-on is flagged as incompatible. Is it normal? (maybe change the manifest to allow all versions)

In addition, I tested with Firefox 28 and its new them Australis, your toolbar is totally broken, no toolbar button.

I created the test add-on for Firefox  25. The button doesn't have an icon so you can only see it if you customize your toolbars to show text. 

I don't know why the button doesn't appear in the toolbar in Nightly. In any case, you should be able to find a button called "File" when you go to Customize. Put it on any toolbar and you'll still see the same results mentioned. 

I'll update the manifest to allow all versions.

I tested with FF8, same issue, so no regression, I guess.
