[Interest] Problem with Loader loaded items showing

[Jason H]

I had a working app with a menu that slides in.
I converted it to use a Loader to load the area that contains the menu and the start page. Now the menu shows up when the app first starts.

Despite my Menu.qml being: 
Item {
	id: menu
	x: -width //I should be off-screen!
	visible: false // you're not visible!!!
	Behavior on x {
		NumberAnimation {
			duration: 250
		}
	}
...
}

qml: loaderState 1
qml: menu.width 480
qml: menu.x -480
qml: root.onCompeleted

It shows and slides to the left. If I comment out the behavior, it works fine. I'm not sure why it's starting at X position 0, when it didn't before. It doesn't look like it is being assigned to zero anywhere in initialization.
