Dear Michael, I don't agree in that the bug should be forwarded upstream, at least not to http://crbug.com/579430 .
First of all, it is stated right in that page that the issue is not really an issue at all (see comments #3 and #5). Moreover, it can't be ignored that the problem arose in 50.0.2661.75-2, so it's quite sure that what is there to blame is Debian way of linking to ffmpeg. The bug is easy to reproduce, so at least it should be acknowledged. Cheers, Paride
