Videos Not Playing in Edge Beta or Stable

All videos on nintendo.com do not play on either the latest stable or beta releases of Edge. For example this page: https://www.nintendo.com/us/store/products/super-mario-bros-wonder-switch/ 

All videos only give the error "Playback cannot continue. No available working or supported playlists."

The same videos have worked fine in both the Canary and Dev builds for a long time, but for whatever reason the fix was never pushed to beta or stable. They do play in beta and stable if "Use graphics acceleration when available" is disabled in Edge settings, but it's not a fix because they then play very slow and choppy. They play in Canary and Dev fine without disabling that option.

Again, not certain why after so long, that the fix from the Dev channel has not yet been pushed to beta or stable. It's been months and months on end.
