This release modernizes the "scroll spy" mechanism to use an intersection observer instead of a window on-scroll handler. This also supports triggering animation when the target element becomes visible for other reasons like a modal opening or a parent div becoming visible, so several options have been renamed and old ones deprecated:
enableScrollSpy-->autoAnimatescrollSpyDelay-->autoAnimateDelayscrollSpyOnce-->autoAnimateOnce
In addition, an onDestroy() cleanup method was added.
