anchorate
Scroll to anchor links.
Scroll to anchor links with client-side routes e.g. with history's listen, React Router's onUpdate, or Gatsby's onRouteChange.
Register a listener to call this and when window.location.hash isn't empty,
it'll scrollIntoView first matching element by id or name per spec.
