The move/rename action for the pages is easier to understand because it has an associated label.
While it is currently not the case for the attachment, this will also be fixed by adding a pagination on the attachments list using the Live Data macro.
It’s not really a blocker, so it’s not required, but it’s also hardly a dangerous change and since 13.10.x is going to be supported for a while, I guess I would be +1 to backport this.
