ListView items sometimes don't reposition correctly if content Y changes before the move

import QtQuick 2.0

Item {
    width: 500; height: 500

    ListView {
        id: view2
        width: 300; height: 300
        y: 100

        model: ListModel {
            id: model2
            Component.onCompleted: {
                for (var i=0; i<30; i++) {
                    append({'name': 'item ' + i})
                }
            }
        }
        delegate: Rectangle {
            width: 100; height: 20; border.width: 0
            Text { text: name + ": " + parent.y }
        }

        Component.onCompleted: {
            //view2.contentY = 80
        }
    }

    focus: true
    Keys.onEnterPressed: view2.contentY = 80
    Keys.onReturnPressed: model2.move(0, 4, 1)

    Rectangle {
        anchors.fill: view2
        border.width: 1
        color: "transparent"
    }
}
