accessibility support for nested h1 in sections?


The HTML5 spec supports nesting sections with h1 headers - see the second  
code example for,-h2,-h3,-h4,-h5,-and-h6-elements,  
which you can play with at

I tested this on my Mac, and found that Firefox, Yandex (chromium-based)  
and Safari all render this visually as if the headers are nested. But none  
of them seem to pass the nested tree to the accessibility API, and in each  
case VoiceOver just treats all the headings as level 1.

Do any windows screenreaders get this right, or is accessibility API  
support lacking here?
