   It also governs the browser's automatic "scroll focused element into
   view" behaviour — on mobile, tapping an accordion trigger while its
   panel is still animating open caused the browser to animate-scroll
   to a stale target position, throwing the opened item off the top of
   the viewport. Only the in-page anchors that want it opt in via
   .scroll-smooth-target below. */
