Offset reporting incorrectly in IE7 on zoom level other than 100%

[smiller.health]

I'm using jQuery 1.3.2 and seeing incorrect results in IE7 on the offset() call when the zoom level is set to anything other than 100%. As a result all elements positioned using data obtained by the results of offset() are placed in the wrong spot. Test case attached.

Here is my first pass at a workaround...

(function($){
    $.fn.zoomOffset = function() {
        var offset = $(this).offset();
        var top = offset.top, left = offset.left;
        var offsetMultiplier = 1;
        if (document.body && document.body.getBoundingClientRect) {
            var bound = document.body.getBoundingClientRect();
            offsetMultiplier = parseFloat(Math.round(((bound.right - bound.left) / document.body.clientWidth) * 100)) / 100;
            if (isNaN(offsetMultiplier)) {
                offsetMultiplier = 1;
            }
            top = Math.round(top / offsetMultiplier),
            left = Math.round(left / offsetMultiplier);
        }
        return { top: top, left: left, offsetMultiplier: offsetMultiplier };
    };
})(jQuery);

This impacts just about every measurement in jQuery so I don't think we can fix it.
