* The tests here basically just checking that the end styles

*
* Relies on the Angular testability only becoming stable once
* animation(s) have finished.
*
* Ideally we'd use https://developer.mozilla.org/en-US/docs/Web/API/Document/getAnimations
* but they're not supported in Chrome at the moment. The upcoming nganimate polyfill
* may also add some introspection support.
