I have a video dom Why does dom execute a onstalled after switching the browser tab before or during resource loading

Now, I just added a retry plan，Is there a better solution?

My goal is to switch the browser tab dom to load the resource successfully

thanks

let dom = document.createElement('video');
dom.preload = 'metadata';
dom.muted = true;
dom.onloadedmetadata = function() {
}
dom.onseeked = function() {
}
let t;
dom.onstalled = () => {
  clearTimeout(t);
  t = setTimeout(function() {
    dom.load();
  },1000);
}
dom.src = url;
