Bugzilla

Release Note Request (optional, but appreciated)
[Why is this notable]: HDR video is a highly requested feature
[Affects Firefox for Android]: No
[Suggested wording]: HDR video playback is now available on Windows (in addition to existing macOS support) - this feature needs HDR mode enabled for the display in Windows Settings - Display. Laptop displays that only offer "HDR video streaming" are not supported at this time.  Some videos recorded on phones in certain orientations are currently not shown as HDR at this time.
[Links (documentation, blog post, etc)]: TBD (will be a foxfooding post for now, and then later a mozillagfx blog post).
