Comment # 1 on bug 1219070 from Jim Taylor

I am having the same problem - youtube videos won't play after Chromium upgrade
to 120.0.6099.216.  Problem was reported to Chromium in Issue 1919587
https://bugs.chromium.org/p/chromium/issues/detail?id=1519587&q=youtube&can=2
and was marked WontFix with "Marking as WontFix since these are distro Chromium
builds, please reach out to your distro for support."  See Chromium bug for
additional details.
