Hi. Because get_innerHTML is not supported on HTML documents. I agree
it would be more correct to return S_FALSE in this case because it's
not an error obviously. As well it should return S_FALSE for non HTML
elements and non HTML documents. However on another hand get_innerHTML
can make sense for HTML documents in contrast to non HTML documents
and elements where get_innerHTML isn't applicable at all. But this
feature was never requested by AT vendors. Which option do you expect?
