Bug description

Posting that with Content Type Markdown results into BE striping away all the content of the Post.

Doesn't seem like it is FE since the POST request does contain the text as intended but returns an empty post.

interestingly enough, BE seems to add the tag to the post tho, just removes it from the content / text
