Description Nikolas Zimmermann 2009-07-27 11:34:58 PDT 
<setvar name="a" value="b"/>
<setvar name="b" value="$a"/>

After substitution, "b" is empty, where it should be equal to "a".
LayoutTests/wml/resources/variable-reference-valid.js contains a FIXME related to that.
manual-tests/wml/variable-substitution.wml also highlights the problem.
