TransformGestureEvent.GESTURE_PAN Event does not fire on Mac OS 10.12.6 Air 27.0.0.130

Example:

trace(Multitouch.supportedGestures);     //gestureZoom,gesturePan,gestureRotate,gestureSwipe

  this.stage.addEventListener(TransformGestureEvent.GESTURE_PAN,function(e:TransformGestureEvent):void{

  trace("tap",e.offsetX,e.offsetY)     //never output

});

This event can fire on Air 26.
