1280509 - Group position broken for XUL tabs after adding two new tabs

Status: RESOLVED DUPLICATE of bug 1515186

(Core :: Disability Access APIs, defect, P3)

Description

STR:
1. Open Firefox.
2. Press control+n.
3. Retrieve the group position information for the accessible of the single tab in the browser tab bar.
Result: 1 of 1
4. Press control+t.
5. Retrieve the group position information for the accessible of the second tab in the browser tab bar.
Result: 2 of 2
6. Press control+t.
7. Retrieve the group position information for the accessible of the third tab in the browser tab bar.
Result: 3 of 2
Note: NVDA sanitises this and reports no group position at all.

Interestingly, if the tab control is created with some tabs already (e.g. you open a recently closed window), the group position info is correct for them. If you then create another tab, it's still correct. Again, it's when you create the second new tab that it breaks.

I think this is a pretty recent regression, but unfortunately, I don't have any specifics.
