Popup with picture-entity RTSP camera stream doesn't unload when closing popup

[abigdeel]

My Home Assistant version: 2022.8.7

What I am doing:
Using browser_mod to replace more_info for camera entities
Use a popup with a picture entity or picture glance card, with a live RTSP link and using webRTC to stream camera
When I close the popup, there is still network traffic.
Re-opening the popup, the stream doesn't start until I kill the webRTC addon or restart HA.

What I expected to happen:
Using custom:frigate-card, there is the option to load/unload cameras lazily.

What happened instead:
Don't seem to have that default behaviour here. Can't stop the stream when pop-up closes.

Minimal steps to reproduce:
Use browser_mod more_info popup with picture entity/picture glance card and using RTSPtoWeb

# The least amount of code or steps possible to reproduce my error

# Put your code/steps here

Error messages from the browser console:
No errors, RTSP stream doesn't end.

// Select everything from the browser console and copy it

// Paste it here

I don't really know if this is a browser_mod issue or if it's just the nature of things.
Not sure where this functionality would need to be added either.

What does work is if I refresh the tab or use browser_mod reload window for Android/tablet sessions. That kills the connection to the stream.

Otherwise, re-opening the card just tries to re-open the stream or sometimes even kicks off another stream. I should mention I'm using go2rtc addon as well to facilitate the RTSP connection via RTSPtoWebRTC addon
