Animation scatters ng-views all around the page

If you click [1] and [2] links by turns, you'll notice that more and more div[ng-view] elements continue to appear on the page.

rc.2 is OK. The regression was introduced by commit 32ad2926116e5f52ed04d788220bd389f8d0a4ac - refactor($animate): use CSS3 transition/animation events instead of $timeouts to track ongoing animations
