Should questions be edited out of answers?

Question

I came across this answer that repeated the contents of the question verbatim. I made a suggested edit that essentially removed the question from the answer.

However, the edit was rejected by the post author on the grounds that it didn't improve the readability of the answer

The edit does not improve the quality of the post. Changes to the content are unnecessary or make the post more confusing.

Obviously, I disagree (hence my suggested edit).

I raised a moderator flag asking for the edit to be pushed through, but was told that this is not something that warrants moderator intervention, which seems reasonable. It was also suggested that I raise this on Meta, so here goes:

What does the community think about questions in answers? Should they be edited out? If so, and the author disagrees, what should be done in that case?

Answer 1

I do think moderator intervention is the easiest way out of this. I've approved the edit (♦ moderators can do this for a while now) and left a comment. The author responded with a plausible reason for rejecting the edit; it turns out they do that in order to avoid downvotes when the question is edited and their post does no longer answer it; such questions are chameleon questions and the Stack Exchange way of avoiding those situations is rolling back the edit to the question.
