reproduction html and video file

A webpage on iOS (iPhone) appears to have a limit on the amount of <video> elements that can be created. Even if old ones are destroyed, the limit remains. This is problematic for code that dynamically changes the DOM and may include videos, because at some point the videos will stop being displayed.

To reproduce, use the attached newvideo.html file. Clicking the button will start a loop that will replace the video element every 3 seconds in a dynamic fashion. At some point, you will just get a video element with the play icon crossed out, and no more videos will play.
