Animate elements into a ListView from outside, despite clip: true for scrolling

In a ListView I have:
{{
addDisplaced: Transition { NumberAnimation

{ properties: "x,y"; duration: 1000 }

}
add: Transition {
NumberAnimation

{ properties: "x"; from: list.finalVrnOrigin.x; duration: 1000 }

NumberAnimation

{ properties: "y"; from: list.finalVrnOrigin.y; duration: 1000 }

}}

It animates the delegate from outside the ListView into the top whilst displacing the list down. With crop set to false, displacing the list down animates the last delegate, if at the bottom of the ListView, down and out of the ListView and over anything beneath it until it finally gets cropped at the screen edge.

With crop set to true, then the add transition becomes meaningless.

I feel this may be/become a relatively common issue and suggest it needs some resolution?
