It sort of reminds me of Slack. There's a variety of situations in Slack where Slack will mutate your message prior to storing it & sending it. (I.e., if you edit the message, it will have changed.) E.g., it will substitute emojis with their short-codes. (And this isn't a valid transformation, and changes some messages, as short codes are not processed inside teletype and code blocks.) Links also get messed around with, often changing or corrupting the link. Code block begin/ends tend to get (annoyingly) merged with the first/lane lines, which makes editing more difficult.
