Basic HTML tags

Here we analyze, which types of HTML tags are allowed inside the content field. Sanitizing fields is desired behavior as seen in Section B.10 of ActivityPub.

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.
