See http://en.wikipedia.org/wiki/Special:ComparePages?page1=A&rev1=&page2=B&rev2=&action=&diffonly= 1. Both revisions are "Latest" but why is one "Revision as of" and another is "Latest revision as of" 2. (undo) - undo what? It always says "The edit could not be undone because it does not exist or was deleted." when clicked. 3. ← Previous edit - which edit is "previous"? Actually this link is broken.
4. [rollback] link
1. Both revisions are indicated as "Latest revision as of ..." now. 2. There is no "(undo)" link 3. There is no " ← Previous edit" link 4. I can't say anything about this, because I don't have the required permissions on enwiki. But I have on Portuguese Wikibooks and I don't see any rollback link here: https://pt.wikibooks.org/w/index.php?title=Especial:Comparar_páginas&page1=Main+Page&rev1=&page2=Teste&rev2=&action=&diffonly=&uselang=en Closing as WORKSFORME (maybe this happened only in MW 1.18 or 1.19?).
