`loadFont()` and `callback` not working properly.

[alterebro]

loadFont() and its callback argument don't seem to work.
Loaded font is only available once the browser has cached the file, which normally happens when you open the sketch for the second time. This behaviour is even present when loadFont() is called within the preload() function.
Also the callback argument is not implemented.

I fixed this issue in q5.js v2, check it out!
https://q5js.org

$.loadFont = (url, cb) => {
  p._preloadCount++;
  let sp = url.split('/');
  let name = sp.at(-1).split('.')[0].replace(' ', '');
  let f = new FontFace(name, 'url(' + url + ')');
  document.fonts.add(f);
  f.load().then(() => {
    p._preloadCount--;
    if (cb) cb(name);
  });
  return name;
};
