[feature] Revert comments

[kriegfrj]

I accidentally edited a comment when I meant to reply/quote it.

There doesn't appear to be an easy way to revert my mistake. I can't delete my edit from the edit history because it is the most recent - I was hoping I could simply delete the edit so that the original post would be visible and my error would be erased from history. And while I can see the original (thanks to the edit history), it's only showing me a rendered output and not the original markdown so I can't even easily copy the original markdown and manually paste it in as a new edit.
