User !important rules should be allowed to override animation rules (for accessibility etc).

It seems that Chromium has started to work on the fix for the same bug in Blink according to https://bugs.chromium.org/p/chromium/issues/detail?id=552085#c14

All !important rules (including author !important) should be overriding animations, per spec:

This is btw the only test failure WebKit has against CSS Cascade 3.
