The CSS 2.1 spec says
(http://www.w3.org/TR/CSS21/visudet.html#abs-non-replaced-width):

"The constraint that determines the used values for these elements is:

'left' + 'margin-left' + 'border-left-width' + 'padding-left' + 'width' +
'padding-right' + 'border-right-width' + 'margin-right' + 'right' + scrollbar
width (if any) = width of containing block

If all three of 'left', 'width', and 'right' are 'auto': First set any 'auto'
values for 'margin-left' and 'margin-right' to 0. Then, if the 'direction'
property of the containing block is 'ltr' set 'left' to the static position and
apply rule number three below; otherwise, set 'right' to the static position
and apply rule number one below."

"1. 'left' and 'width' are 'auto' and 'right' is not 'auto', then the width is
shrink-to-fit. Then solve for 'left'"

"Calculation of the shrink-to-fit width is similar to calculating the width of
a table cell using the automatic table layout algorithm. Roughly: calculate the
preferred width by formatting the content without breaking lines other than
where explicit line breaks occur, and also calculate the preferred minimum
width, e.g., by trying all possible line breaks. CSS 2.1 does not define the
exact algorithm. Thirdly, calculate the available width: this is found by
solving for 'width' after setting 'left' (in case 1) or 'right' (in case 3) to
0.

Then the shrink-to-fit width is: min(max(preferred minimum width, available
width), preferred width)."


According above algoritm Webkit, Firefox, Opera renders it properly. IE renders
it incorrectly. The bug is INVALID.
