I flagged a comment to one of my answers and then deleted the answer. Then I went to my flagging summary and was surprised to see that my flag has been marked as helpful. Went back to the post and seensaw that the comment was still here.
Ok. To check my assumptions, I've flagged the comment again, and then undeleted-deleted the answer. The flag has been marked as helpful again.
Is it intentional though? I did flag the comment because it contained sensitive information, and I did want it to be removed, regardless of whether my answer is deleted or not.
