https://chat.stackexchange.com/?tab=site&host=chat.gaming.stackexchange.com doesn't work as expected. I thought it would show me the chatrooms related to Gaming SE, but I only saw the Web Apps SE room. Another user saw the XMPP chatroom and nothing else.
host does not include
chat., works correctly.
This wouldn't be too big of a deal except that that first URL was automatically generated when I entered http://chat.gaming.stackexchange.com/ into my browser by hand.
