In that case, I think it would be good to update the spec to clarify this.

Agreed. I think that if you create an animation in the paused state,
you would expect that all aspects of the animation remain frozen until
it's unpaused.

There's also the question of whether an animation which is created in
the paused state should immediately fire its start event if the delay
is non-positive. I think it's clear that firing the start event should
be tied to displaying the first value, so if we're to specify that
such an animation should immediately display a value, I think it
should also immediately fire the start event.
