That hits the issue in 2.5, right? If the :hover state is removed before the
element has achieved its full size, the element will instantly take its full
size (ugh!) and transition back to normal.

I was also thinking about additive animations. I guess that's not a huge
issue since in CSS, style rules applying to the same element always override
one another, rather than add, so authors who need additive effects need to
introduce extra elements anyway. Still, might be worth noting somewhere that
additive effects are a non-goal since IIRC SMIL has them.
