Description

Any bubbling event with type 'resize' causes a stack overflow in Flex SystemManager/Stage_resizeHandler() method.
This issue was discovered because Flash CS3 component fl.controls.Label dispatches a bubbling ComponentEvent with
colliding 'resize' type when autoSize is set to non-'none' value.

Steps to reproduce:
Compile and run this MXML:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
addedToStage="dispatchEvent(new Event('resize', true));"/>

Actual Results:
Error: Error #1023: Stack overflow occurred.

(...)

Expected Results:
Invalid resize event is ignored.

Workaround (if any):
function cancelResize(event:Event):void
{
if (event.target != stage)
event.stopImmediatePropagation();
}

stage.addEventListener('resize', cancelResize, false, int.MAX_VALUE);
