Seems more like a bug in Opera8 to me. The dl has no position:relative, if you
would add that, then it would act the same as Opera.

I've done some reading and I think you're right. The dl in my testcase isn't a
containing block. See: http://www.w3.org/TR/REC-CSS2/visuren.html#q29 Does this
mean that absolute positioned childs do not generate overflow?

And thanks for the tip!

Per the current CSS2.1 draft, we should not be clipping those elements, and a
current build in fact does not.

Opera's behavior here is wrong.
