I believe that fixing Firefox/Gecko to match the spec is the best  
solution. Safari 3 beta has already shipped with behavior that  
conforms to the spec, with substantial developer evangelism about this  
issue. (See, e.g., this recently published tech note: http://developer.apple.com/technotes/tn2007/tn2177.html#CANVAS) 
. Reversing the spec, and re-reversing our course to return to Safari  
2 behavior, would be terribly confusing. (I'm not even sure that it's  
possible at this late hour.)

Thanks,
