This patch performs a lazy calculation of the before change style once
it has been determined that a transition is being retargeted. In doing
so, the current position is correctly updated to reflect changes made
via the web-animation API. The path also addresses a bug in the
calculation of current time, in the case of a paused or play-pending
animation.
