title: Can an equals sign appear after the first equals sign in a query parameter?
body: <p>For example, is this a valid URL:</p>
  
  <p><code>http://0.0.0.0:8080/auth/reset?id=AAAAAAAAAAA=&amp;code=uX8kklWhVi-Vhp4BdMRQYBEveEdwQXBFDecLlsT6yBw=</code></p>
  
  <p>From what I've researched it seems to be discouraged (but I haven't found anything definitive), but all the decoders I've tested it with decode it correctly. This includes:</p>
  
  <ul>
  <li>Google Chrome</li>
  <li>Firefox</li>
  <li>NodeJS' <code>decodeURIComponent</code></li>
  </ul>
