Example URL:
https://jsfiddle.net/pjx9vogu/2/

Steps to reproduce the problem:
1. Open https://jsfiddle.net/pjx9vogu/2/
2. The video plays on hover and pauses when you are no longer hovering
3. Move the mouse around to play and pause the video
4. Now, leave the page open in a tab and go do something else
5. Come back after a couple of minutes and try playing the video again by hovering
6. If it doesn't break, go do something else for a few more minute before coming back

What is the expected behavior?
The video should play again after coming back and hovering over the video. Both Firefox and Safari play the video correctly after coming back.

What went wrong?
In Chrome, after coming back and hovering, the video will play for a little bit then immediately stop playing and will no longer play. The error property on the video element is then filled with a MediaError of code 3 and message of "PIPELINE_ERROR_DECODE: video decoder reinitialization failed". I've attached the log from chrome://media-internals

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes
