It seems as if this bug has much to do with bug 355078.
since i do not know if this is the same, i just post my screenshots of a site which show the behaviour. the iframe itself is rendered properly, but the iframe-scrollbar is rendered solely above the layered span-area.

Reproducible: Always

Steps to Reproduce:
1. embed an iframe with abolute width and height in the site which conteins enough content so that scrolling is necessary and the scrollbar appears 
2. position absolute some colored span area above the iframes scroll-controls; use z-index (even in its highest value) to position the span area on absolute top
3. recognize that scrollbar of iframe is rendered on top of span-area in spite of a logically lower z-index

Actual Results:  
optically bizarre appearance of iframes which are covered by absolutely positioned span areas

Expected Results:  
to not see the iframe and its controls if they are covered by a span area

see expected results
