title: Form field not found when executing feature file in Behat with Selenium
body: <p>I'm running a Behat feature file where I try to select an option in a form field</p>
  
  <pre><code>When I select "Lisa Hayes" from "settings_custom[Counselor][]"
  </code></pre>
  
  <p>where "Lisa Hayes" is one of the values in form name "settings_custom[Counselor][]". The element details are as follows:</p>
  
  <pre><code>&lt;select id="settings_customCounselor" name="settings_custom[Counselor][]" multiple="multiple" size="4" class="valid"&gt;
  &lt;option value="" selected=""&gt;(does not matter)&lt;/option&gt;
  &lt;option value="685572"&gt;Lisa Hayes&lt;/option&gt;
  &lt;option value="685573"&gt;Ricky Hunter&lt;/option&gt;
  &lt;option value="685574"&gt;Max Sterling&lt;/option&gt;&lt;/select&gt;
  </code></pre>
  
  <p>I get an error when I execute the feature file on the command line</p>
  
  <blockquote>
    <p>Form field with id|name|label|value "settings_custom[Counselor][]" not found.</p>
  </blockquote>
  
  <p>My default driver is selenium2 (I have selenium-server-standalone-2.32.0.jar server running in the background and my browser is firefox).</p>
  
  <p>Note that this works perfectly when I change my default driver to goutte (headless) from selenium (web driver).</p>
  
  <p>I tried to search this forum and Googled for any specifics and did not find any helpful information.</p>
  
  <p>Let me know if you need more information. Thanks!</p>
