Markdown/inline links don't work unless URL starts with http(s)

I figured I can't have been the first to notice this but I can't find any specific mention, and it still trips me up every so often.

If I want to link to Tildes, I can type
http://tildes.net,
https://tildes.net, or
www.tildes.net,

and they format automatically. Simply tildes.net (or blog.tildes.net) doesn't automatically turn into a link, which makes sense.

However, if I do inline links, only the first two will work:

Tildes (http), and
Tildes (https).

Tildes (www) results in Error 422 (Unprocessable Entity), topic_id36: String does not match expected pattern.
Tildes and Tildes (blog) do the same.

I saw the link canonicalization issue on GitLab but I don't know if this would fall under that.
