Missing metadata and disordered events from YouTube

[exbotanical]

I'm on arch running the following command while playing YouTube videos (Brave browser)

playerctl -F metadata -f '{{title}}\{{artist}}\{{status}}\{{position}}\{{mpris:length}}\{{mpris:artUrl}}'

Whenever I switch to a new video by clicking on the thumbnail, I notice two things:

• the mpris:artUrl metadata goes missing
• messages appear [ostensibly] out-of-order. I know YouTube does some weird stuff with iframes, so maybe this is just on them

Here's sample output. You can see when I change the video, YouTube sends 'paused' events, then sends several events from the new video, a few more from the old one, then finally the new video with missing metadata.

If I stop the command and re-run, I start seeing all of the metadata again.
