SectionStack Section visibility

[Chris_A_Wood]

The code below shows a sectionStack Section with 2 VLayouts one of which has its visibility set to "hidden" but it still shows. This can also be reproduced with in the smartclient samples page. Could this be considered a bug?

	isc.SectionStack.create({
        visibilityMode: "multiple",
		height: "100%",
		width: "50%",
        sections: [
            {title: "Section 1", expanded: true, items: [
                isc.Label.create({contents:"Introduction", height: 20}),
                isc.Label.create({contents:"Variable Data Rules", height: 20}),
				isc.Label.create({contents:"Technical Specifications", height: 20})
            ]},
            {title: "Section 2", ID: "IDPackagingItemsHeader", expanded: true, items: [
				isc.VLayout.create({
					backgroundColor: "green",
					members:[
						isc.Label.create({contents:"Barcode Stickers", height: 20}),
						isc.Label.create({contents:"Printed Fabric Labels", height: 20}),
						isc.Label.create({contents:"Tickets", height: 20})
				]
				}),
				isc.VLayout.create({
					visibility: "hidden",
					backgroundColor: "yellow",
					members:[
						isc.Label.create({contents:"Kids", height: 20}),
						isc.Label.create({contents:"Ladieswear", height: 20}),
						isc.Label.create({contents:"Menswear", height: 20})
				]
				})
            ]}
        ]
    })
