title: Routing to same page with anchors
body: <p>I'm new to react router and currently implementing a page with navigation.
  The top part is navigation followed by content part.  </p>
  
  <p>Currently when someone clicks on <code>localhost:8080/page</code> it renders a component in the content part. 
  On click on one of the nav items page redirects to <code>localhost:8080/page#my-anchor</code> also the content below renders another component. </p>
  
  <p>When clicking back button, the URL changes to <code>localhost:8080/page</code> but the content doesn't get updated. </p>
  
  <p>How to handle the update of content with browser back &amp; forward buttons? </p>
