title: When submitting a GET form, the query string is removed from the action URL
body: <p>Consider this form:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;form action=&quot;http://www.blabla.com?a=1&amp;b=2&quot; method=&quot;GET&quot;&gt;
      &lt;input type=&quot;hidden&quot; name=&quot;c&quot; value=&quot;3&quot; /&gt; 
  &lt;/form&gt;
  </code></pre>
  <p>When submitting this <code>GET</code> form, the parameters <code>a</code> and <code>b</code> are disappearing.<br />
  Is there a reason for that?<br />
  Is there a way of avoiding this behaviour?</p>
