Comment 43 for bug 602877

I'll have to look into this, but my guess is that in FF 3.5, yes, it got focus events, and that after the large focus manager rewrite, no it does not. I think this behaviour change is also the cause of some of the other issues we're seeing in FF, even with this patch. However, from the discussion above, it's not clear if it's a bug or not for "heading1" to receive focus events. That's why I didn't test for it, as the correct behaviour still sounds in dispute. I'll find time this week to verify all this.
