738666 - Videos can occasionally be in perpetually loading stage, even when you can play them fine

Status: RESOLVED DUPLICATE of bug 738401

(Core :: Audio/Video, defect)

Attachment: screenshot with some videos always loading

This seems to be a regression in Aurora 13: I didn't notice this on Aurora 12.

Basically, it seems like under certain circumstances, the video element will be in a perpetually loading stage. It seems to only happen when a video is added to the DOM dynamically, though I'm not 100% certain. I first noticed this here here:

(click on one of the datapoints to get a video which reproduces the problem)

I tried to narrow down the problem with a standalone test case:

If you click on the button repeatedly, eventually you'll get another video in the same state (see attached screenshot)
