Console log after screen share permission prompt would no longer display on getDisplayMedia calls

Occasionally when calling 'getDisplayMedia' the permission prompt will fail to display.  Safari will have the permissions for 'screen sharing' set to 'ask' but the prompt fails to display.  More significantly, when the page is reloaded the permission prompts for 'getUserMedia' will also fail and the page is unable to access either the microphone or camera regardless of what the user sets the permissions to via the settings menu.  I was able to force this behavior after several minutes of calling 'getDisplayMedia', canceling the 'screen share', and then calling 'getDisplayMedia' again (also muting/removing the audio or video track during this forced sequence of steps as well). Our QA people have reported this occurring in with some frequency during their normal testing work.  

I used meet.jit.si (with two users [one on each of two machines]) as a public setup to forcefully reproduce this issue. 

Safari Version 16.2 (18614.3.7.1.5)
