Actually, I think that IE 6 actually does return a cloned document,  
Mozilla returns null and Opera throws an exception.  I've patched  
selfhtml.js so that it will attempt to do a brute-force copy of the  
host document if Document.cloneNode(true) doesn't work.  That allows  
IE 6, Mozilla, Opera and Safari to all run the same test, but they  
each take a slightly different path through the supporting test  
framework code depending on their responses.

I've submitted bug 4174 (http://bugzilla.opendarwin.org/show_bug.cgi? 
id=4174) with a patch and more notes.
