At the very least, when horizontal scrolling isn't the more common use to drag a map with a "hand" pointer? In that case there is a natural mapping without any need to grab a (thin) scrollbar, if there even is one. On mobile, with such a drag operation, I suppose one could place a finger between menu items so as to not select anything while dragging.
