Problem Description: From Safari Technology Preview 177, do the following

1. Run following webRTC sample from github that shows how to call getDisplayMedia() API to start a screen share.

https://webrtc.github.io/samples/src/content/getusermedia/getdisplaymedia/

2. Click the "start" button, and select the 'Allow to Share Screen' option from the menu that pops up

3. Nothing happens : i.e, screen is not shared.

4. If, at step 2, you select "Allow to Share Window", then the shared window is displayed correctly. So the bug only seems to affect the "screen share" functionality.

5. Similar behavior is observed through other webRTC applications such as Jitsi


Note: same test works fine on Safari 17.0 on the same machine

I can reproduce this on STP177, This does not reproduce for me on STP 178.
