When I try to roll back an edit to a comment, the rollback silently fails.
Steps to reproduce:
1.Start a new thread
3.Edit the comment as an IP
4.Log back in
5.Go to recent changes, and click the rollback link at the end of the rc line for your IP edit
You are taken to the thread's page, but the edit is not undone
The IP edit should be undone.
This is on MW1.16 beta 3 with r67097 of LiquidThreads.
