Description

Steps to reproduce:
1. Create instance of SkinnableContainer or any of its subclasses (BorderContainer, spark:Panel) at runtime.
2. Add child to this newly created container before adding it to stage
3. Add instance of SkinnableContainer to display list
4. trace(child.owner)

Actual Results:
contentGroup in a skin

Expected Results:
SkinnableContainer

Workaround (if any):
Add child only after container complete creation. Or use mx: alternative of a component.

Still reproducable in SDK 4.1

Code to reproduce the issue:

var p:BorderContainer = new BorderContainer();
var b:Button = new Button();
b.label = "Test";
b.addEventListener(MouseEvent.CLICK, function (e:Event):void
{
trace(b.owner); // traces Test0.ApplicationSkin2._ApplicationSkin_Group1.contentGroup.BorderContainer107.BorderContainerSkin110.Group111
});
p.addElement(b);
addElement(p);
trace(b.owner); // traces Test0.ApplicationSkin2._ApplicationSkin_Group1.contentGroup.BorderContainer107.BorderContainerSkin110.Group111

The problem is in SkinnableContainer.partAdded method. It should unsubscribe from _placeHolderGroup ELEMENT_REMOVE event before removing the elements from it.
