To give you a specific example, I have asked this question, but then realized it must be a bug in the software and created this bug report. The bug was quickly fixed, but the question itself remains unanswered.
My first intuition was to delete the question, because it is no longer relevant. But keeping it may be beneficial for other people wondering, like me, if the buggy behaviour was there for a reason and they missed something in the documentation.
I checked that the bug was introduced in the release from Dec 30, 2020 and the fix is yet to be released, which gives quite a few misbehaving versions out there. Thus right now I lean more towards answering the question.
What would you recommend, answer my own question, or delete it?
