Comment bug

When making a comment, if I highlight the text and hit the quote button, it replaces/erases the full text and just put in a >

When doing the same it the post dialog, it works normally, quoting each paragraph at once, so it is just in the comment box that it isn't working.

Also, while I'm here, is User Tagging in any of the future plans? I try not to block people because even their bad takes can inspire some good conversation, but if I can have an idea when I'm looking at someone I've already seen is trollish or has consistently bad opinions, that can save me some time deciding to deal with them or not. I've never used this feature before, but I've seen other people mention their apps had this and it sounded useful.

Thank you for all you do!
