We fixed this in current WebKit sources and will not insert a <tbody>.  
However, the table will still render as expected because per CSS we  
will create an anonymous table body on the rendering side only, no  
element. So some future release will match the Opera 9.21 behavior,  
which I believe is correct.

I suspect testing error here, since IE would refuse to render  
application/xhtml+xml.
