> Workaround (if any):
> There are 3 possible fixes for this bug.
> 1. SystemManager.as - line 1811, the contains() method is excluding
> children with an index below the current value of the "noTopMostIndex"
> property when the popupChildren IChildList's children start at this value.
> This prevents any interested objects from using the contains() method on the
> SystemManager to check for popupChildren existence (@see MenuBar.as line
> 1679).
> 2. SystemChildrenList.as - line 110 and 121, addChild() and addChildAt()
> methods fail to check if the DisplayObject being added is already a child of
> owner before incrementing the upperBoundReference. This causes subsequent
> calls to those methods throw a RangeError.
> 3. PopupManagerImpl.as - line 307 fails to check whether or not the
> displayObject being popped up is already a child of the IChildList instance
> before calling addChild().
> Any of the fixes mentioned above would solve this problem but for brevity, I
> have attached a monkey patch for the SystemChildrenList.as with the repro
> project.
