Closed-then-merged question missing “closed by” and “merged to” footers
https://stackoverflow.com/questions/8607022/can-i-create-a-custom-text-field-and-keyboard-for-ios-w-o-subclassing-uicontrol has been migrated from Code Review, where its status displays correctly. On SO, however, it seems to be closed as a duplicate, or more accurately a double-post.
The thing is, it wasn't closed by anyone:
The Ghost of Christmas Future, maybe?
The timeline view isn't any help either. It just shows Community adding the duplicate link. Also note that there is no link to /revisions displayed, despite it existing. As NullUserException อ_อ ♦ points out below, however, the revisions page does indeed show the correct history: Will ♦ closed, merged, and locked the post about an hour before I came across it.
Is this actually a bug, or does Community perhaps look for exact duplication of title and/or body when a question is migrated (as I said, the migration turned this into a double-post on SO)? If so, shouldn't there at least be a "Closed by Community ♦" banner added?
