Description

Steps:
1. Create custom mxml component extending Window
2. Put a lot of content there ex. 200 <mx:Canvas width="100%" height="100%"/>
3. Instantiate class open & close
var customWindow:CustomWindow = new CustomWindow();
customWindow.open();
customWindow.close();

Actual Results A:
windows is not closed

Actual Results B:
with more content there is chance that one a while I'll get error on app start (in this case I was closing splash window)
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.core::Window/enterFrameHandler()[\frameworks\projects\airframework\src\mx\core\Window.as:3064]

//FRAMEWORK CODE
private function enterFrameHandler(e:Event):void
{
if (frameCounter == 2)
{
removeEventListener(Event.ENTER_FRAME, enterFrameHandler);
_nativeWindow.visible = _nativeWindowVisible; // <--- HERE _nativeWindow is null

Expected Results:
window will close correctly

Workaround (if any):
override close method and check if window is already initialized
