overflow:auto does not work with CSS3 transformed child elements. Suggested workaround?

Problem: css3 transforms applied to a child element inside a div are ignored by the browser (FF5, Chrome12, IE9) when calculating the scrollHeight and scrollWidth of the containing div's scrollbars when using "overflow: auto;".

<style type="text/css">
div{ width: 300px;height:500px;overflow:auto; }
div img {
-moz-transform: scale(2) rotate(90deg);
-webkit-transform: scale(2) rotate(90deg);
-ms-transform: scale(2) rotate(90deg);
}
</style>    
<div><img src="somelargeimage.png" /></div>

I have put together a small test on jsfiddle showing the undesired behavior.

Essentially I am trying to create a simple web based image viewer using css3 transforms for rotate and scale and would like a containing div with fixed width/height to be able to scroll to see the full content of the image it contains.

Is there an开发者_开发百科 intelligent way to handle this issue, or even a rough workaround? Any help is appreciated.

I added an extra div to each of the transformations and by setting fixed widths for those divs and clipping overflow I manged to make them the correct size. But then I had to use position: relative and top: blah; left: blah to shift the images into the correct position. http://jsfiddle.net/4b9BJ/7/
