Change internal shortcode to support experimental non-standard browser lazy loading

That would be great, Bep.

Just as a side note (feel free to move my little suggestion into a new topic):

Browsers will support (and some already do) native lazy loading.

Maybe it would make sense to support this (now or later) along with the new intrinsicsize parameter in the Hugo figure shortcode.

Wow @Grob, that’s exciting. Though, I already can imagine the pain of waiting for other browsers to adopt it. Until they do, we will still have to create fallbacks manually.
