Extra HTML Tags

This set of HTML tags contains tags that are probably safe to support, but not necessary for Note objects. Here, we take the attitude that a Note is something akin to a a microblogging post.

The ✅ means that the html tag was left unchanged. ❓ indicates the content was changed, by hovering over it, one can see into what.

❓ for misskey is due us not supporting checking markdown yet.
