I see your concern. Form what I read from the source, active is only touched when some new element got activated (controlled through bool allowActiveChanges = !oldActiveElement && activeElement();). My manual test also confirms that removing this check did not make active element to change on mouse move, but hovered element changed as it should. Have a look at http://jsbin.com/onomul/3/edit

Maybe a new unit test could help us out here? But I'm not sure what or how exactly it should test because this behavior doesn't seem to have any tests, does it?
