I'd have to page `position:sticky` information back into my brain, but I can answer the second one, because it was needed for Acid2. When building display lists, we keep track of display items that were supposed to go on top of `position:fixed` and layerize them. This matches what WebKit does. Note that we don't implement pseudo-stacking contexts correctly (and neither does WebKit).
