Is this a lack of functionality in ADE and Kindle, or is there a workaround?

body
{
counter-reset:section;
}
h1
{
counter-reset:subsection;
}
h2
{
counter-reset:subsubsection;
}
h1:before
{
counter-increment:section;
content:"Section " counter(section) ". ";
}
h2:before 
{
counter-increment:subsection;
content:"Topic " counter(section) "." counter(subsection) " ";
}
h3:before 
{
counter-increment:subsubsection;
content:"Area "counter(section) "." counter(subsection) "." counter(subsubsection) " ";
}

I think you found one of the CSS things that is not part of the EPUB spec, but works in some viewers

Rule of thumb: don't count on these kinds of Features, they will fail when you most need them
