Please describe the bug

On some browsers youtube iframe links are dead (Error 153). Youtube changed their iframes pretty recently but it seems adding the referrer attribute fixes the problem. It doesn't work for me on Macos edge (but works on chrome firefox and safari).

Do you see any errors in console log?

How to reproduce the issue?

1. View a message with a youtube link

What do you expect?

The iframe to not give an error

What actually happened?

The iframe got a 153 error

Do you have any screenshots or recordings to repro the issue?

No response

Adaptive Card JSON

Additional context

No response

No source file or test is named in the issue. Start by locating the code that renders YouTube iframes, reproduce the Edge failure with a message containing a YouTube link, and verify that the requested referrer policy is present and the iframe no longer shows the reported error.
