This seems like a bug to me, but it may be that I misunderstand the feature.
I recently made an edit to an answer (it was in fact a rollback that I deemed worthy), and as per usual I forgot to give a reason for my edit. Normally this wouldn't bother me as any edits I make are usually obvious as to why they have been made, but in this case (a rollback) I felt it important to give my reasons why.
So I clicked the "Edit" link under my rollback - which by the way had a current auto-generated description like "rollback to revision 2" - I added in my "Edit Summary" and then clicked "Save Edits". It submitted fine, but the description was not changed. I tried this a second time with the same results.
Is this the expected behavior for this action? In which case I assume it's because there is no change to the code/title/tags?
If it is working "as designed", then I would suggest that the user is notified with a warning that this edit will not have any effect, giving the reasons why.
I think the best way to replicate this issue/query is as follows:
- Go to the edit history for a post you have previously edited
- Click the "edit" link under the heading of your edit
- Change (or add) an "Edit Summary"
- Click "Save Edits"
It should appear successful (it submits fine), however no change will have been made
