so I finally get to make the ruby text/furigana shitposts I've always wanted to make but apparently this is not supported in comments.
Because it's not supported in comments, I also tried looking to see if Markdown extensions for ruby text exist, and they apparently do in some implementations, but none of them have been implemented/work on Cohost, which is very understandable
EDIT: It has come to my attention that there is a list of allowed elements for chosting, which is very handy
