Run the code as specified in QTBUG-10675 (not QTBUG-10671).

Note how the blue rectangle jumps to the top left corner the third time it is clicked instead of executing the transition.
N.B. adding

    State {
        name: ""
        ParentChange { target: blueRect; parent: whiteRect; x: 5; y: 5; width: parent.width-10; height: parent.height-10}
    },

to as an explicit state does not help.
