I'm using opera gx and I definitely still get this. It's really annoying because I can hop into a google meet call with someone, and it would prompt me for permission to show the camera at the beginning. And then maybe 40 minutes later I lose my ability use my camera and microphone again.
Even worse is location permissions, I'd have websites that prompt me to allow location permission, and it doesn't matter if I select the allow this time, or allow forever options, or even store it in the settings for the site. Allowing just does not work, and reloading the page makes opera prompt me again.
