Lighten the DOM category by introducing a new HTML one, containing:
- inert attribute
- popover attribute
- Vertical form controls
- HTML <model> element
- HTML <model> document
- lazy image loading (<img loading=lazy>)
- lazy iframe loading (<iframe loading=lazy>)
- dialog element
- PDF.js (functionality wise similar to HTML <model> document, but also this is behind a build flag off by default, so doesn't matter where it goes as long as it can be turned on)
