It's always been you, Canvas2D

There are some getters and setters in the web APIs with cheeky side effects. Presumably this one causes the canvas to be re-created, or something. Here's another good one, try it in your browser console:

    location.href = location.href;

Your trick doesn't work for me in Firefox 96 :)

One more: If you set an image's src attribute to the same thing, it'll still reload the image.

  const image = new Image("/img.png");
  document.body.append(image);
  image.src = image.src;

It might not actually reload the image but it has to fire all the events as though it did otherwise code would hang.

It does reload the image in Firefox at least. I just tried it.

Oh, it works, it's just cheekier than you think - it won't refresh the page if the URL includes a hash/fragment (such as after you clicked one of the "next" links while browsing comments here).
