I am trying to use PrinceXML to create booklets from lecture materials. However I stumbled upon some strange CSS-problem:

I am using two nested relative positioned divs. However, if the embedded div is longer than a page, it gets cropped at the bottom - i.e. some of its contents disappear.

See e.g.
This PDF-file on page 13 (Source, CSS)

I guess I am doing something terribly wrong - though I do not quite get what...

Any ideas?
