I just ran into this Suggested Edits review item. The changes made are good, I would like to use Improve Edit to polish it a little more. What makes this item special is that the edit comment definitely falls under "rude or offensive." If I approved or improved that edit, the summary comment would require a custom moderator flag to remove, and that would be unfortunate.
Since this specific edit was proposed an anonymous user (with no rep on the line), I copy-pasted the revised Markdown from the Improve Edit box to the Reject and Edit one, causing the edit to be unilaterally rejected. Is that always the right thing to do?
