replaceChild() on documentElement causes scrollbars to not work in iframe.

[caseyjor]

I suspect that messing with the documentElement in this manner is
probably a no no but it would really help if when I did this ( in
firefox 3.x ) :

document.replaceChild(new_document_element, document.documentElement);

I didn't lose the function of my scrollbars.

BTW: new_document_element is a document fragment generated from an
xslt transform. The transforms owner document is set to the document
doing the replacing.

Any ideas?

Thanks!
