Yesterday, I saw this question pop up on Stack Overflow. At the time, the question's title was something about "zero-width lookahead not working".
An hour later, it had a new title. The question's history doesn't reveal any edits to that effect. At first I thought the question was deleted and then re-posted with a new title. So I searched my browser's history, found the original question and made sure it had the same ID.
Is there a way to hide edits from others? Is this a bug?
(Yes, I am 100% sure that the question initially had a different title and no, I cannot provide any screenshots with freehand cirlces.)
