Hidden Event Fired When Backdrop Still Hiding

Created by: trevorharwell

I would expect the hidden event to fire once the modal AND the backdrop have been animated out. I had a bug where one modal was trigger as soon as another was hidden and the second modal never fired because the modal backdrop was still animating. I changed the event to only fire once the backdrop was hidden as well and the issue went away. If you do not like to the idea of changing how the hidden event works then at least have another allhidden event or something like that.
