Two blocks with "float: right; clear: right" are positioned with respect to each
other even when they are in different block formatting contexts.  CSS2 seems
vauge on this, but the CSS 2.1 spec specifically says:
"The 'clear' property does not consider floats inside the element itself or in
other block formatting contexts."
( http://www.w3.org/TR/CSS21/visuren.html#propdef-clear )

Mozilla 1.5 did this positioning correctly, 1.8a2 does not.

Reproducible: Always
Steps to Reproduce:
See example.

Actual Results:  
Red box is positioned beneath green box.

Expected Results:  
Red and green boxes are positioned next to each other.

They're not in different block formatting contexts.

block formatting context != block

(And what would have changed the testcase was fixing bug 148994.
