Acid3 expects <html> margins to not affect absolute positioned elements

See the @font-face test (the map::after generated content).

Hixie claims that:
http://www.w3.org/TR/CSS21/visudet.html#containing-block-details

justifies that absolute positioned elements should ignore margins on <html>.  I
tried to build a test case, but I couldn't get a <div style="position:
relative; left: -20px; top: -20px;" to actually move itself up into the margins
of the HTML (I could get it to move left into the left margin).

FF seems to behave identically to us in this regard.
