title: crbug/1173575, non-JS module files deprecated on Chrome Extension
body: <p>I have a custom chrome extension that has a SSO login enabled, so, for use the extension, the user has to login with the corporate accout.
  The SSO login is an external URL (Microsoft login), so, for the login, when the extension start:</p>
  <ol>
  <li>I check the login.</li>

  <p>After this, if I close the extension and open it another time, the extension works with no problem because the user is properly logged.</p>
