As Monty discovered, Firefox does not make the poster disappear until the
video is played. Feel free to file bugs against any browsers that behave
differently; just because the spec allows something doesn't mean it's a good

Tightening up the spec to require the poster to remain until the video is
played does sound like a good idea.

We do need a spec change to allow the poster to be shown when the video has
ended, if that is the most commonly desired behavior.

they received the message with great eagerness and examined the Scriptures
every day to see if what Paul said was true." [Acts 17:11]
