I did say "bottom right", rather than "bottom". :)

Ok.

So, the way I understand it, the margins of the last <p>, .inner, and body
collapse. This results in an effective margin on body of -3em. So the
testcase should render as if .inner and <p> didn't have margins, and the
body had margin-bottom: -3em -- which should place the large blue box and
the blue square at the very bottom of the scrollable area, i.e. *not*
leaving any space at the bottom.

Am I missing something?
