--- Comment #12 from evawillms <evawillms183 at gmail.com> ---
Issue still reproducible on Safari version 15.1 (15612.2.9.1.30, 15612).

Another way to reproduce:
* Open https://webrtc.github.io/samples/src/content/capture/canvas-video/https://run3online.pro
* Using mouse, move teapot on the left side around, by holding down left-click and dragging your mouse around
* Notice that teapot on the right doesn't mirror the left teapot's movement

I wonder if issue is due to auto-play constraint violation.  Console logs follows.

MediaElementSession::clientWillBeginAutoplaying(74E6F415461C6466) state = Autoplaying
HTMLMediaElement::setShouldDelayLoadEvent(74E6F415461C6466) true

MediaElementSession::autoplayPermitted(74E6F415461C6466) Returning FALSE because element is not visible in the viewport
MediaElementSession::removeBehaviorRestriction(74E6F415461C6466) removed RequirePageConsentToLoadMedia, interruption count = 0
