 * I believe this plugin / the JS library used is relying on jQuery’s scroll which**
   cannot** presently implement passive scroll listeners.
 * This leads to a recommendation in PageSpeed to use passive scroll listeners.
 * Is it possible to use IntersectionObserver or recommend the underlying library
   to use it instead of on on jQuery for scroll event primarily? i.e. IntersectionObserver
   can be the 1st choice if available and jQuery’s scroll as fallback.
