Videos restart with every fragment

[gregreen]

In a slide with a video and fragments, the video restarts every time a new fragment is shown. Here's a minimal example:

<section>
  <video style="width:50%;" data-autoplay loop data-src="video.mp4"></video>
  <p class="fragment">fragment 1</p>
  <p class="fragment">fragment 2</p>
</section>

Interestingly, the video does not restart when you go backwards in the presentation and hide fragments.

It would be nice to have an option to prevent the video from restarting every time a new fragment is shown. There is a similar issue with background videos.
