AppletStageExtension - When defaultclose is overriden after closing Applet is not restored.

Example:
var rectangle:Rectangle = Rectangle {
    x: 100
    y: 100
    width: 100
    height: 100
    fill: Color.RED
    onMouseClicked: function(e: MouseEvent): Void {
                    s.close();
    }
}

var s: Stage = Stage {
    title: "AppDeploy Demo"
    width: 300
    height: 200
    style: StageStyle.TRANSPARENT
    opacity: 0.5
    scene: Scene {
        content: [
            Text {
                content: bind textContent
                x: 25
                y:35
                fill: Color.BLACK
                font:Font{
                    size: 24
            }},
            rectangle
        ]
    }
    extensions: [ AppletStageExtension {
            shouldDragStart: function(e: MouseEvent): Boolean {
                return e.shiftDown and e.primaryButtonDown;
            }
            useDefaultClose: false
            onAppletRestored:function (){
                isAppletRestored = true;
            }
     } ]
}

Take this code. After dragging out Clicking on the rectangle suppose to take Applet back to Browser.
Actual Behaviour:
a) Applet is not visible after clicking the rectangle .
b) isAppletRestored variable is still false. Means onAppletRestored is not called .
