I recently asked the question Was Narcissa Malfoy a Death Eater?. To my surprise, it was marked as a duplicate of What Happened to the Malfoys after the Second Wizarding War?, despite them seeming to me like very different questions. As far as I can tell, the reason was because the second question's accepted answer had, by its own admission, "a tenuously related fact" that happened to be the answer to the first question.
This seems to go against the message of the duplicate, which says "This question has been asked before and already has an answer", since the question itself has not been asked before. This conflicts with one comment for the question, which stated that "We close questions as dupes based on previous questions or answers."
Besides, the policy on duplicates states that sometimes duplicates aren't closed: "We love (some) dupes. There are many ways to ask the same question, and a user might not be able to find the answer if they're asking it a different way." I think that even if this were a duplicate, this question would fall under that category.
Should this particular question have been closed because an unrelated question (from my point of view) contains the answer?
