Pseudo-join from mention in a new room shows you as reading the message
Sometimes when you get a mention, it can sorta join you to that room and add it to your left menu temporarily with "Leave" and "Hide" options. This also seems to have the side-effect of counting you in the readBy
even though you haven't joined the room.
I say sometimes because, the first time I tested, everything worked smooth: The user mentioned, the room disappeared from the left menu after reading the mention. If the mention was scrolled off-screen, it just had the "hide" option which all seems correct to me.
Thanks to @abhisekp for finding this one!
