Enabling WebCodecs Origin Trial causes the screen sharing not to work properly

Meeting SDK Web
1

Description
We were advised to enable WebCodecs and SharedArrayBuffers origin trial to solve some of the issues we are facing with Web SDK 1.9.6 like the delay in showing own video.

When I tested with just the WebCodecs origin trial enabled, I noticed that although the “delay in showing on video” issue has been fixed with that, a new issue appeared which is the screen sharing is no longer working properly. When I started screen sharing, preview is not shown on the screen sharing preview box inside the green bar of the page (this is the green bar showing when you do screen sharing on web client SDK). The black screen is also shown on the other user’s screen instead of the screen that I am sharing.

And then, when reported to Zoom, we were advised to enable SharedArrayBuffers origin trial as well together with WebCodecs. But when I tested with both the origin trials enabled, the issue is still there.
