Setting contentX on Flickable is ignored.

[Kysymys]

Hi there,

In the following source, setting the contentX property is ignored.
Can anyone tell me why?

@
import QtQuick 2.0

Rectangle {
width: 360
height: 360

Text {
    anchors.fill: parent
    text: "Info:"
          + "\n contentX:" + flickable.contentX
          + "\n contentWidth:" + flickable.contentWidth
          + "\n width:" + flickable.width
}

Rectangle {
    id: container

    anchors.top: parent.top
    anchors.right: parent.right
    anchors.margins: 10
    width: 200; height: 100;
    color: "lightsteelblue"

    Rectangle {
        id: touchArea
        
        anchors.top: parent.top
        anchors.left: parent.left
        anchors.bottom: parent.bottom
        width: 50
        color: "cornsilk"
    }
    Flickable {
        id: flickable

        anchors.top: parent.top
        anchors.left: parent.left
        anchors.bottom: parent.bottom
        width: 50

        contentWidth: draggable.width
        contentHeight: draggable.height
        
        // This seems to have no effect at all
        contentX: 100

        Rectangle {
            id: draggable
            width: 150;
            height: flickable.height;
            color: "#30ff0000"
        }
    }
}

}

To add to the confusion:
if you move the Flickable into the Rectangle (touchArea) and use the fill anchor, everything works as expected.

@
import QtQuick 2.0

Rectangle {
width: 360
height: 360

Text {
    anchors.fill: parent
    text: "Info:"
          + "\n contentX:" + flickable.contentX
          + "\n contentWidth:" + flickable.contentWidth
          + "\n width:" + flickable.width
}

Rectangle {
    id: container

    anchors.top: parent.top
    anchors.right: parent.right
    anchors.margins: 10
    width: 200; height: 100;
    color: "lightsteelblue"

    Rectangle {
        id: touchArea
        
        anchors.top: parent.top
        anchors.left: parent.left
        anchors.bottom: parent.bottom
        width: 50
        color: "cornsilk"

        Flickable {
            id: flickable

            anchors.fill: parent

// anchors.top: parent.top
// anchors.left: parent.left
// anchors.bottom: parent.bottom
// width: 50

            contentWidth: draggable.width
            contentHeight: draggable.height

            // This is set just fine
            contentX: 100

            Rectangle {
                id: draggable
                width: 150;
                height: flickable.height;
                color: "#30ff0000"
            }
        }
    }
}

}

Since I've not become any smarter and the community doesn't seem to have an answer too, I've issued this as a bug.
