Can YouTube be treated as an audio channel by the system?

I listen to podcasts on YouTube frequently, and with YouTube Premium I can turn off the screen and keep listening. Typically when audio is playing and there's an interruption - say navigation instructions or a workout app reporting lap times - the audio will briefly pause then resume once the interruption is over. This doesn't happen for YouTube, presumably because it's not being treated the same by the system (audio channel vs. audio/video channel?), so the "high priority" audio plays overtop of the video's audio. Is it possible to change this behavior so videos (or at least their audio) pause during these alerts? On YouTube or across the system?
