Details

As of today's mozilla-central [1], before-change style is the value that has been already updated at the *current time* if the target element has already animations there.  That's because we are doing cascading process in animation-only restyle (bug 1361938).  
To get the correct before-change style, we have to store rule nodes at the previous style change event somewhere and cascade this previous rule nodes with animation rules nodes which are updated at the current time.

I have no idea how to do this effectively.
