I can reproduce in Firefox 48 but not in 49.

Awesome, thanks.  Will a fix be backported to 48, or should I just wait for 49?

WebM/EME isn't supported in 48. Are there any production sites that use Shaka player with WebM but don't require EME?

Unfortunately, I don't know the answer to that.  As an open-source project, we only know details of production apps if their authors happen to tell us.

We have many WebM assets in our demo app, and we run automated tests over those assets.  Our tests are failing on Firefox, so it would be nice if we could see them passing sooner.  But it's not critical, and we can wait for 49.
