Someone kindly pointed out to me off-list that you - Alex - are the  
one working out of those bugs.

My apologies for not noticing this!  It's late, and I need sleep.

I'm more curious about your original motivations now - if MathML  
support is in the engine, couldnt accessibility roles also be worked  
on that would expose it to *all* screen readers, instead of one  
designed specifically to be some sort of WebKit "add on"?
