These issues might have a place in technical interviews, but framing it as a question the user can get "wrong" feels a bit like you're setting a trap. In a real interview, this would just be a talking point. What would be interesting to an interviewer would be seeing how quickly the interviewee grasps what's happening that is unexpected, and why. Marking the candidate down because they didn't know about these quirks beforehand is kind of missing the point.
