Hmm, I think you are right. I think it needs to go into "paused for
user interaction" state in step 5 of the media playback algorithm at
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#media-playback
rather than calling the video's "pause" action. Eric, Philip, what do
you think?

Yes, I have the same issue and have asked that question in email. But
it might be worth filing a bug.
