This works as expected in Firefox. It doesn't work in IE 11 because of a bug in IE 11's accessibility implementation. I'm not sure whether we can work around this yet.
Technical: IE 11 doesn't expose the focused state when aria-activedescendant is used, though it does fire a focus event. I don't think we want to just stop checking the focused state altogether for IE. I guess we could walk up the parents looking for aria-activedescendant, but that's pretty slow.
