Save yourself time by going to the URL provided for reproduction.. or:
1. create a div with a large image inside it
2. apply 100% height to both div and image
3. apply absolute or fixed positioning to wrapping div
4. resize browser window
 optionally:
- apply a background color to div to confirm actual size of div is incorrect
- change the position of the div to right:0

EXPECTED: The surrounding collapsed tags should have dimensions equal to the internal resized image.

INSTEAD:
When the wrapped image is being resized, the surrounding wrapper incorrectly uses the natural image width instead of the resized image dimensions. This places the resized image in an incorrect position when window is resized.

Depending on your screen resolution, the rendering might seem fine.. please resize your browser window to see if your renderer is affected

As of August 3rd 2010, most popular engines are affected with the following exceptions:
- In process of being fixed in the Gecko engine: https://bugzilla.mozilla.org/show_bug.cgi?id=582037 
- Webkit renders correctly until window is resized, however if user modifies zoom/font-size (ctrl+/-) the wrapper width is corrected again.
- Opera/9.80 (Macintosh; Intel Mac OS X; U) Presto/2.6.30 Version/10.60 - Renders correctly until window is resized however Windows version is affected like all others (Windows NT 6.1; U)
