Property changes undo order

[ixSci]

Hi!

In today's qml I observe the following case:
e.g. we have some state with some changes:
@State{
name: "something'
PropertyChanges{...}//1
ParentChange{...}//2
}@

And when item transits into that state those changes will be applied in 1->2 fashion and will be undoed(in the case of transition into the default state) n the reverse(2->1) fashion. I have not found any documentation about that order.
And my question is: Can I expect this behavior in the next versions or it is a subject to change?
