title: Panels not visible in React Storybook
body: <p>I am using <a href="https://storybook.js.org/" rel="noreferrer">Storybook</a> version 3.3.15 on Windows 7 running node version 6.3.1 and npm version 3.10.6. </p>
  
  <p>On running storybook, I see 'No panels Available' message in the bottom of the page where actions panels are rendered. I have imported <code>addon-actions</code> in addons.js: <code>import @storybook/addon-actions/register</code> and the module is also present in <code>node_modules</code> folder. I am not getting any errors regarding this during webpack compliation or in browser console. </p>
  
  <p>How do I make the Action Panel appear?</p>
  
  <p>Note: I cannot update the Node and NPM versions because I am working on a professional level app wherein lots of people are involved and its a very big codebase. </p>
