title: Images are not displayed with DOMPDF with HTTPS
body: <p>I'm creating a pdf with DOMPDF and it's working fine on local and in a server with HTTP but when the source is in a server with HTTPS the images are not displayed.</p>
  
  <pre><code>$options-&gt;set('isRemoteEnabled', TRUE);
  $dompdf = new Dompdf($options);
  
  $context = stream_context_create([ 
      'ssl' =&gt; [ 
          'verify_peer' =&gt; FALSE, 
          'verify_peer_name' =&gt; FALSE,
          'allow_self_signed'=&gt; TRUE 
      ] 
  ]);
  $dompdf-&gt;setHttpContext($context);
  </code></pre>
