Testcase shows the behaviour of absolutely positioned element is not complied with W3C standard.

Safari Version       : 4.0.3 (531.9.1)
Other browsers tested:
Chrome 4.0.213.1: Same as Safari
     Firefox 3.x: Same as Safari
          IE 6/7: Different to Safari
            IE 6: Different to Safari

What steps will reproduce the problem?
1. Launch the testcase file attached

What is the expected result?
The inner div is absolutely positioned div without left/top specified. So according to W3C standard, its left side should be at the place as same as static positioned div.

W3C standard: 
http://www.w3.org/TR/CSS2/visudet.html#abs-non-replaced-width
  "2. 'left' and 'right' are 'auto' and 'width' is not 'auto', then if the 'direction' property of the element establishing the static-position containing block is 'ltr' set 'left' to the static position, otherwise set 'right' to the static position. Then solve for 'left' (if 'direction is 'rtl') or 'right' (if 'direction' is 'ltr')."

What happens instead?
The inner div always align to left of the outer div, which is different from the static flow. ( The first and third groups in testcase are absolutely positioned while the second and fourth groups are static positioned for comparing. )
