Thanks for opening, I also noticed this myself recently that this stopped working!

I'm in the same situation.

Change the loadedmetadata event to the playing event, and then get around it for now.
But no autoplay.

Time setting is held off until a canplay event occurs, function currentTime.

Change the loadedmetadata event to the canplaythrough event that occurs after the canplay event

https://github.com/mediacms-io/mediacms/blob/main/frontend/src/static/js/components/video-player/VideoPlayer.jsx#L195

    player.player.one('canplaythrough', () => {       
      const urlParams = new URLSearchParams(window.location.search);
      const paramT = Number(urlParams.get('t'));
      const timestamp = !isNaN(paramT) ? paramT : 0;
      player.player.currentTime(timestamp);
    });
