Can't send HTML or Markdown statuses

[CPlusPatch]

Every time I use postStatus, there is no way for me to set the content-type as "plain", "markdown", "html" or anything else.

I have analyzed the HTTP requests performed by Megalodon and they are missing the content_type POST parameter, which is text/plain on normal messages.

Is it allowed?
Can you send markdown or HTML on WebUI?

[CPlusPatch]

Absolutely, I use Akkoma (Pleroma fork, same API) and I can send Markdown or HTML or MFM messages from within the default web interface

What happens when you send Markdown or HTML in the message? It is rendered as HTML in the timeline?
When I post markdown text in Mastodon, it is not rendered as HTML, it is rendered as plain text: https://mastodon-japan.net/@h3poteto/109930646032098298

I use Akkoma (a Pleroma fork) and Calckey (Misskey fork) which render HTML text as HTML

Besides, Mastodon has just merged support for HTML text rendering as well (mastodon/mastodon#23913)
