Resolves: #19104
Description
The behaviour described in the linked issue occurs due to two operations being requested on the domains collection:
In most cases, we aren't sorting as well as saving, so we can short-circuit and not publish the second notification when we aren't making any changes to sort order.
When we are sorting, it's strictly correct to publish two notifications as we are making two separate saves.
