IOS Screen recording issue - does not capture audio from videos when using a browser

I can screen record from apps on my iPhone and the audio is captured as well. When I try to screen record using Safari, Firefox, Chrome or other lesser known browsers the video is captured without the audio. I know how to activate the iphones buit in microphone to capture external audio. I don’t want that. I only want to capture the videos audio that I am Screenrecording online.

It looks like this has been an ongoing bug with surprisingly few solutions offered up online. Have spent all day seeking a solution without luck.

Any ideas?
