PopUps after reparenting displayobject to new Window still show in Main Window

Question

Hello,
I am working on an attach/detach functionality in AIR where a user can export a displayobject from the main application into a separate air mx.core.Window.
However, even once the object has been reparented into the native window, all its pop ups and tooltips continue to display in the main window.
Let me display this with a simple example:
Sample Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.core.Window;
  [Bindable]
  private var cdata:Array = ["Test1", "Test2", "Test3"];
private function popout():void
        var popoutWin:Window = new Window();
        popoutWin.addChild(cc);
        popoutWin.open();
]]>
</mx:Script>
  <mx:HBox>
  <mx:Button label="PoP" click="popout()" />
      <mx:Canvas id="cc">
      <mx:ComboBox id="cb" dataProvider="{cdata}" />
      </mx:Canvas>
  </mx:HBox>
</mx:WindowedApplication> 
If you popup "cc", you will always see the dropdowns in main window instead of the new window. If you popup "cb", it will behave only as long as you had not opened the combobox before. (probably because the systemManager property used by the PopupManager gets set to that of the native window only for the root component that gets moved) 
Any help would be highly appreciated.

Which version of the Flex SDK are you using?  I just tried this with AIR 2 and Flex 4.1 and the combobox menu displayed in the secondary window (though it did require two clicks.)
