21127	Selected categories displayed out of order on main edit screen	CircleReader		"(First time submitting a ticket...)

Fixed for Quick Edit in #19474, this is still happening in the main edit screen. Selected categories float to top upon updating the post, losing their visual relationship with other categories. 

1. A selected child category, if the parent is not selected, is removed from its place under its parent and shown as a parent at the top of the list.
2. If both a child category & it's parent are selected, both float to the top, and the parent-child relationship is preserved visually.
3. In both cases, unselected categories remain orphaned at the bottom, with unselected child categories no longer shown as children.  "	defect (bug)	closed	normal		UI	3.4	normal	duplicate
