Bug Problem with qouting users with @ in front of their names

I have a user with @ in front of her name. And, there's also user with same name, but just without @ i.e. @some_user_name and some_user_name.

Problem is when user gets quoted. It's parsed inside quote part, user without @ gets mentioned. You could try on your site. Maybe you corrected this in v3.

I do believe I did, v2.x is no longer supported unfortunately
