Known specifics

sortIndex numbers might not start at 0. The moved item gets a number one greater than that of the afterItemId item, and the number of the afterItemId item does not change. If the first of two sub-items numbered 0 and 1 is placed after the second, their numbers become 1 and 2. Item order depends on how the numbers compare, not on whether they are consecutive.
