Automatically describe mention type in HTML

[jonnyandrew]

Problem

To help with rendering of mentions, web clients attach attributes to the HTML link tag <a> to identify the link as a mention and keep track of it's type. Now that this library is responsible for parsing Matrix mentions, this is no longer necessary.

Solution 1

• Move from <a> tags to custom html tags for mentions #714

Solution 2

Depends on

• Parse Matrix mentions from HTML #692
• which is partially implemented in Add Matrix mentions utils [wip] #695

Given some mentions are parsed by the library into a mention nodes:

<a href="https://matrix.to/#/@test:example.org">test</a>
<a href="https://matrix.to/#/#test:example.org">#test:example.org</a>

When I get the internal content as HTML (get_content_as_html()), it should have the data-mention-type attribute with an appropriate value (room or user):

<a href="https://matrix.to/#/@test:example.org" data-mention-type="user">test</a>
<a href="https://matrix.to/#/#test:example.org" data-mention-type="room">#test:example.org</a>

Note that get_content_as_message_html() should not return this attribute.
