You're absolutely right; it turns out this is a difference between CSS
2 and CSS 2.1.
If you look at section 9.5 in CSS 2.1, they cut the bit about explicit
width, and if you compare sections 10.3.5 in both documents, they say:
in CSS 2:
If 'left', 'right', 'width', 'margin-left', or 'margin-right' are
specified as 'auto', their computed value is '0'.
in CSS 2.1:
If ’margin-left’, or ’margin-right’ are computed as ’auto’,
their used value is ’0’.
If ’width’ is computed as ’auto’, the used value is the
"shrink-to-fit" width.
