Today I asked this question and one user (I'll call them UserA for differentiation) in the comments helped me get through my issue and gave me the answer to fix my issue, but it was left as a comment. A user (UserB) an hour or more later then just used UserA's comment as an answer with a extra fluff around UserA's comment.
My intuition says downvote since to me that is stealing.
Although I am aware that it could be seen as, UserB did not see the comment; they just happened to appear to be copying.
