Oh, sorry.

greping for "rowspan=\"0\"" in  
http://www.paciellogroup.com/blog/2012/04/html5-accessibility-chops-data-for-the-masses/  
and http://dotnetdotcom.org/ I find the following pages being broken in  
Opera but working in Firefox/Chrome:

I stopped after going through about half of the matches. All of these are  
quirks mode. I didn't find any that work in Opera/Firefox but are broken  
in Chrome (i.e. rely on it being unsupported in standards mode). I didn't  
find any that work in Opera but are broken in Firefox/Chrome (i.e. expect  
it to work in quirks mode).

This is enough to convince me that the feature should not be supported in  
quirks mode.
