title: Storybook does not refresh after save
body: <p>I have created a Storybook and after when I change something and save it, the browser does not refresh automatically. So every time I have to press the F5 button. Unfortunately, I could not figure the problem.</p>
  <p>I start the storybook with:</p>
  <pre><code>yarn storybook
  </code></pre>
  <p>The repository is hosted on <a href="https://github.com/softshipper/react-storybook" rel="nofollow noreferrer">https://github.com/softshipper/react-storybook</a>.</p>
  <p><strong>Update</strong></p>
  <p>I have figured out that on Firefox hot reload works like a charm. However, on Chromium hot reload does not work at all. I am using <a href="https://pop.system76.com/" rel="nofollow noreferrer">https://pop.system76.com/</a> as OS and Chromium is installed with flatpak.</p>
  <p>When I start the storybook, in the terminal it shows me:</p>
  <pre><code>$ start-storybook -p 6006
