parenResized does not execute

[jumple]

v10.0d and v9.1

Not sure if this is a bug or I am doing something wrong but I can not seem to catch parentResized event in this code. Resizing Window triggers "resized" event but not "parentResized" on a child

isc.Window.create({
	canDragResize:true,
	resized: function(){
		alert("resized executed")
	},
	items:[
		isc.Canvas.create({
			parentResized: function(){
				alert("parentResized executed")
			}
		})
	]
})
