Reviewed by Antti Koivisto.
Fixed some issues with the interaction between CSS animations/transitions and
anchor positioning:
* The style to be saved when deferring updating/applying animations should also
be the starting style, in addition to the previous render style.
* Updating/applying animations should be deferred until a position option is
chosen.
