Bug: Scaling DisplayObject with TextField Child

Question

Hi,
my app has a number of DisplayObjectsContainers of type Sprite. Among others, these objects each have a TextField as their child. Scaling the Sprite object does not properly scale its child TextField. Also, in case the Sprite object is not scaled directly, but indirectly by adding it to a scaled Container, AIR 2.6 shows the same behaviour on the iPad. renderMode is set to gpu.
Seems to me like a bug, since the same code runs properly on desktop and on android.
How can this be solved??
Thanks in advance

So I'm the only one with this problem? I still hope to get some feedback on that one.
Below is a small class that shows the problem. Just add it to your project, instantiate it and put it on the stage. Don't forget to set renderMode to gpu and let it run on iPad and on other platforms. You see the difference?
Here's the code:
package
    import flash.display.Sprite;
    import flash.events.TimerEvent;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.utils.Timer;
    public class TestScale extends Sprite
        private var ScaleObj:Sprite;
        private var TF:TextField;
        private var _timer:Timer;
        private var _scale:Number = 1.0;
        private var _dir:int = 1;
        public function TestScale()
            super();
            this.graphics.beginFill(0x333333);
            this.graphics.drawRect(0,0,500,500);
            this.graphics.endFill();
            ScaleObj = new Sprite();
            ScaleObj.graphics.lineStyle(1,0x000000);
            ScaleObj.graphics.beginFill(0xeeeeee);
            ScaleObj.graphics.drawRoundRect(0,0,150,40, 6,6);
            ScaleObj.graphics.endFill();
            ScaleObj.x = 100;
            ScaleObj.y = 100;
            TF = new TextField();
            TF.width = 140;
            TF.x = 4;
            TF.y = 5;
            TF.defaultTextFormat = new TextFormat("_sans", 15, 0x000000);
            TF.text = "Just a scaling test";
            TF.selectable = false;
            ScaleObj.addChild(TF);
            addChild(ScaleObj);
            _timer = new Timer(200);
            _timer.addEventListener(TimerEvent.TIMER, onTick);
            _timer.start();
        private function onTick(event:TimerEvent):void
            _scale += 0.1 * _dir;
            if(_scale > 2.0 || _scale < 0.2)
                _dir = _dir * -1;
            ScaleObj.scaleX = _scale;
            ScaleObj.scaleY = _scale;
Thanks in advance for any helpful input!!
Best regards
