title: Refresh the page only once in react class component
body: <p>I have a react app with a page with a class component on it. What I want to do is to refresh that page only once when you first load it, but all that I have tried, with window.location.reload() for example, ends up in a infinite refresh loop. Does anyone know how to do this? I a functional component I do like this, and it works :</p>
  <pre><code> useEffect(() =&gt; {
      if(reloadCount &lt; 2) {
        sessionStorage.setItem('reloadCount', String(reloadCount + 1));
        window.location.reload();
      } else {
        sessionStorage.removeItem('reloadCount');
      }
    }, []);
  </code></pre>
  <p>but if I convert it for class component, like this, it doesn't work :</p>
  <pre><code>componentDidMount() {
      if(this.reloadCount &lt; 2) {
        sessionStorage.setItem('reloadCount', String(this.reloadCount + 1));
        window.location.reload();
      } else {
        sessionStorage.removeItem('reloadCount');
      }
    }
  </code></pre>
  <p>Any idea how to do this in react class components ?</p>
  <p>P.S. I want to do this because I use a mapbox component that saves the previously initialized map to the DOM, so when the user return to the page containing the map, there's no need to initialize the map again. But now I have this map on another page too, and if I navigate between the 2 pages  containing the map, it keeps the css from the previous page, and it's messed up. And the only way I can work around this is to force refresh the page.</p>
