title: Google Pagespeed Insights (Lighthouse) is telling that I'm not using jquery
body: <p>On the <a href="https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fautocustos.pt" rel="nofollow noreferrer">report</a> of Google Pagespeed Insights on my website I get this suggestion:

  <p><a href="https://i.stack.imgur.com/3nzg4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3nzg4.png" alt="enter image description here"></a></p>
  
  <p>When I use the <code>Coverage tab</code> on Chrome Dev tools, just 30% of the <code>jquery.min.js</code> file is not used</p>
  
  <p><a href="https://i.stack.imgur.com/7QiHV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7QiHV.png" alt="enter image description here"></a></p>
  
  <p>Therefore I have the following questions:</p>
  
  <ul>
  <li>If the file <em>is used</em>, why am I getting this suggestion? A bug?</li>
  <li>Am I supposed to split the jquery file in two, and load initially just the used part? I've never seen that.</li>
  </ul>
