IF you exaimine the full tree of accessible in the test case for bug 381602 you will find that the first element of the single select and multiple select claim focuse at the same time as well as another odd accessible. Since the FOCUSED state means the accessible has the keyboard focus, and there can be only one such focus this seems like a bug.

Cc'in Neil in case this bug pops for him.
I think this may have to do with us forcing the first item of a list to be focused for jaws. I'm also not sure that this actually ever hurts anyone.
