[TransformManager deleting TargetObject on backspace]

When I set item.hasSelectableText=true, and then edit a TextField not managed by TransformManager and hit the backspace, TransformManager deletes the current selected item.

 

I stopped TransformManager from doing this by changing the following code in TransformManager

 

private static function onKeyPress($e:KeyboardEvent):void {
           _keysDown[$e.keyCode] = true;
           if ($e.keyCode == Keyboard.DELETE ){        //|| $e.keyCode == Keyboard.BACKSPACE) {
           	_keyDispatcher.dispatchEvent(new KeyboardEvent("pressDelete"));
           } else if ($e.keyCode == Keyboard.SHIFT || $e.keyCode == Keyboard.CONTROL) {
           	_keyDispatcher.dispatchEvent(new KeyboardEvent("pressMultiSelectKey"));
           } else if($e.keyCode == Keyboard.UP || $e.keyCode == Keyboard.DOWN || $e.keyCode == Keyboard.LEFT || $e.keyCode == Keyboard.RIGHT) {
       		var kbe:KeyboardEvent = new KeyboardEvent("pressArrowKey", true, false, $e.charCode, $e.keyCode, $e.keyLocation, $e.ctrlKey, $e.altKey, $e.shiftKey);
       		_keyDispatcher.dispatchEvent(kbe);
           }
}
