Details

The spec for this says it should return an iterable, and the object it returns has an iterable name. Also it is iterable on Chrome.

But Firefox 104 has a syntax error indicating that it is not. You can see this by running the example here on both platforms: https://pr19990.content.dev.mdn.mozit.cloud/en-US/docs/Web/API/CSS_Font_Loading_API#font_loading_with_events#result_2

document.fonts.ready.then(function() {
  
  log.textContent+=(`\nFontFaces in document: ${document.fonts.size}.\n`);

  for (const fontFace of document.fonts.values()) {
    log.textContent+='FontFace:\n';
    for (const property in fontFace) {
      log.textContent+=`  ${property}: ${fontFace[property]}\n`;
    }
  }
});

This is not a new issue - it appears in the intenet from around FF60:

I think Emilio was looking at this in bug 1729089.
