In fact, in the given example Opera inserts a "stroke-dasharray" attribute
with an empty value, so this serialization use-case would not work in Opera.

I don't think there's any real utility to authors for requiring an empty
attribute to be inserted into the DOM for animations to run, and I strongly
object to the browser automatically inserting one, on the grounds that the
DOM belongs to the author and browsers shouldn't modify it just to make
implementation easier. I hope Erik confirms this is just a small Opera bug
:-).

Serializing the current state of the animation would be an interesting
feature, but I think the default should be that content round-trips intact.
For example an editor for animated images would NOT want this when saving an
animated image.
