Found in Bugzilla after bug 455886 landed: If an HTML:label has both a @title attribute and inner text: 1. The inner text becomes the accName for the label as usual. 2. The contents of the @title attribute becomes the accName of the control this label is associated with via the @for attribute. This is a regression.

This demonstrates the problem. Look at the accName of the label and the combobox, they should be identically called "Country:", but aren't. The same can be observed in Bugzilla on any bug with the "Wanted-next" and other such blocking/wanted/etc. flags. And the factor is the title of the label rather than the title of the combobox, as in Bugzilla the same title is present on both controls. I reduced the testcase to the actual problematic constellation.

the problem is nsTextEquivUtils::AppendFromAccessible is called on label accessible and gets the label name. Since reqursive name from subtree is denied then we do not get name from subtree for label and get its name from @title attribute.
