title: Ionic/React Router sometimes load page sometimes not
body: <p>i have an issue with Ionrouter, to be precise i think it is the IonTabBar which produce the error.
  For example my router looks like this:</p>
  <pre><code>&lt;IonReactRouter&gt;
  &lt;IonTabs&gt;
    &lt;IonRouterOutlet&gt;
      &lt;Route exact path=&quot;/tab1&quot;&gt;
        &lt;Hub /&gt;
      &lt;/Route&gt;
      &lt;Route exact path=&quot;/Course&quot; &gt;
        &lt;Course&gt;&lt;/Course&gt;
      &lt;Route path=&quot;/profilepage&quot;&gt;
        &lt;ProfilePage /&gt;
    &lt;/IonRouterOutlet&gt;
  
    &lt;IonTabBar slot=&quot;top&quot;&gt;
      &lt;IonTabButton tab=&quot;tab1&quot; href=&quot;/tab1&quot;&gt;
        &lt;IonIcon icon={triangle} /&gt;
        &lt;IonLabel&gt;Tab 1&lt;/IonLabel&gt;
      &lt;/IonTabButton&gt;
      &lt;IonTabButton tab=&quot;Course&quot; href=&quot;/Course&quot;&gt;
        &lt;IonIcon icon={triangle} /&gt;
        &lt;IonLabel&gt;Course&lt;/IonLabel&gt;
      &lt;/IonTabButton&gt;
      &lt;IonTabButton tab=&quot;Profilepage&quot; href=&quot;/profilepage&quot;&gt;
        &lt;IonIcon icon={person} /&gt;
        &lt;IonLabel&gt;Profile&lt;/IonLabel&gt;
      &lt;/IonTabButton&gt;
    &lt;/IonTabBar&gt;
  &lt;/IonTabs&gt;
  &lt;/IonReactRouter&gt;
  </code></pre>
  <p>If i reload page i cant get to <code>/Course</code> anymore. If i edit <code>&lt;Course&gt;&lt;/Course</code> and change it to <code>&lt;Hub&gt;&lt;/Hub&gt;</code> and then change it back to <code>&lt;Course&gt;&lt;/Course&gt;</code> i can get to load all pages fine again. What is Wrong? all other pages working only <code>/Course</code> is awkward.</p>
