+  The position of the top border edge of the div#clear-left
+  is where it would have been if the element had a
+  non-zero bottom border. The margins of div#clear-left
+  collapse together to 140px and the top border edge of
+  div#clear-left is at 40px inside of it. Clearance is
+  added at such position, not to the whole 140px.
