That requires UAs to always compute the value of animation properties on 
all elements, including in display:none subtrees.

In particular, this requires performing selector matching and so forth 
on those elements, which is something UAs commonly optimize out now.

I don't believe that this is desirable.  Unless I'm missing something here?
