HTML tags in summary

Here we analyze, which types of HTML tags are allowed inside the summary field.

As the content field, the [summary field(https://www.w3.org/TR/activitystreams-vocabulary/#dfn-summary) is described as

A natural language summarization of the object encoded as HTML.

This is a somewhat petulant table as most Fediverse applications treat the summary field as a plain text content warning.

Sanitizing fields is desired behavior as seen in Section B.10 of ActivityPub.
