Define a -scrollViewSibling property/outlet on the accessory view and point it to the document view. The NSView -enclosingScrollView override can check for a response to scrollViewSibling and conditionally send -enclosingScrollView to it. That way you are only overriding the -enclosingScrollView behaviour for views whose response is considered defective.
