[FF] scroll to wrong position on writing

Hi,
hope someone can help me with this problem I have with Firefox.

I have the editor with a MozTransform scale factor, but then when I write something down the document, the browser scroll me in the wrong place; with pageDown button I have the same problem, the document scrolls down but not to the real end of the enlarged document, but to the end of the document without the transformation.

It seems that Firefox don't consider the zoom scale factor.

Is there anyone who can help me out with this problem?

Thanks


ps: to reproduce this bug after the CKEDITOR.replace part add (content should be long enough to scroll):

CKEDITOR.on('instanceReady', function(ev){
            var body = ev.editor.document.getBody().$;
            body.style.MozTransformOrigin = "top left";
            body.style.MozTransform = "scale(1.5)";
            body.style.OTransformOrigin = "top left";
            body.style.OTransform = "scale(1.5)";
            body.style.TransformOrigin = "top left";
            body.style.Transform = "scale(1.5)";
            // IE
            body.style.zoom = 1.5;
        });
