      Scroll the view downwards and observe that the delegates are not deleted as they move past the top of the view. This issue does not occur if the first item's height is > 0.

      (Note, however, if the view is scrolled upwards, items that scroll past the bottom of the view are indeed deleted. The issue only occurs for items moving up past the top of the view.)

      import QtQuick 2.0

Item {
    width: 500; height: 500

    ListView {

        id: view2
        width: 240; height: 320
        x: 100
        y: 100


        model: ListModel {
            id: model2
            Component.onCompleted: {
                for (var i=0; i<40; i++) {
                    append({'name': 'item ' + i})
                }
            }
        }
        delegate: Rectangle {
            width: 200; height: index == 0 ? 0 : 20; border.width: 1
            Row {
                Text { text: name + " : " + index + " : " }
                Text { text: " " + parent.parent.x + ", " + parent.parent.y }
            }
            objectName: name
        }

    }

    Rectangle {
        anchors.fill: view2
        color: "lightsteelblue"
        opacity: 0.7

    }
    Text { anchors.right: parent.right; text: "content y:" + view2.contentY + ", count: " + model2.count }

}
