Today, I just realized that when you onebox a link in chat, the referral tail is removed.
For example, if I try to onebox http://meta.stackexchange.com/q/9134/178438
, it links to http://meta.stackexchange.com/questions/9134/jon-skeet-facts
(Evidence that I used a referral link)
Could this be fixed? Sharing a link in chat obviously counts as "shared a link".
