Github onebox should show branch name

When a github link to a “different than master” branch is posted, the onebox should somehow show the branch name.

Here is an exmaple from Proposal: Consolidated Review Queue :

From this preview i understand that this is on and i would expect the branch to be the master branch, which is not correct as the branch is named reviewable: (Also observe that in the inline link, the branch name is shown correctly).


This is still not the case … I am putting PR welcome on this, seems fine if the branch is not there by default, only when a specific non master branch is linked.
