Part of the desire here was 

> authors should be able to achieve the same positioning behavior for their own elements.

so if we allow the abspos behavior, we should also add some new CSS to allow authors to apply this to their own elements. That's not something I relish doing, since we'd then probably need the same special-casing for all the properties that force containing-block-for-positioned-descendants (filters, transforms etc).

This is a strong argument to just go with the fixed pos approach. Do we know if the "should be able to scroll the dialog out of view" behavior is a strong requirement? Who came up with it?
