I don't think that's at-all clear from the HTML 4 spec though I agree it 
can be read that way. In general, having long debates about the exact 
intent of the HTML 4 spec isn't really an interesting way to spend time 
so, unless their are clear bugs (some examples of which have been raised 
already), I don't plan to change the "HTML 4" algorithm in the table 
inspector. However I am interested in hearing about ways to improve 
heading association and will endevour to implement reasonably-detailed 
suggestions for algorithms as separate options for people to try.
