title: jQuery Validate setDefaults not working after upgrade
body: <p>I have recently upgraded my jQuery from 2.1.3 to 2.1.4 and jQueryValidation from 1.13.0 to 1.14.0 after that my jQueryValidation defaults stopped working. Not giving any error on console.</p>
  
  <p>Here's debug findings:</p>
  
  <pre><code>// http://jqueryvalidation.org/jQuery.validator.setDefaults/
  setDefaults: function( settings ) {
      $.extend( $.validator.defaults, settings );
  }
  </code></pre>
  
  <p>At this point before extending <strong>$.validator.defaults</strong> value is:</p>
  
  <p><a href="https://i.stack.imgur.com/D1w6e.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/D1w6e.png" alt="$.validator.defaults"></a></p>
  
  <p>and after <strong>$.extend</strong>, <strong>$.validator.defaults</strong> value is : </p>
  
  <p><a href="https://i.stack.imgur.com/6Bx4H.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6Bx4H.png" alt="$.validator.defaults with my settings"></a></p>
  
  <p>This means that defaults settings are updated according to my given settings. But end result is not what is expected. Here's the generated code:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div class="form-group"&gt;
         &lt;label class="col-sm-5 control-label"&gt;Experience &lt;small&gt;(in years) &lt;/small&gt;&lt;/label&gt;
         &lt;div class="col-sm-7"&gt;
              &lt;input name="ctl00$ContentPlaceHolder1$EmployeeSkillExperience" type="text" maxlength="4" id="ctl00_ContentPlaceHolder1_EmployeeSkillExperience" class="form-control error" required="required" aria-required="true" aria-invalid="true"&gt;
              &lt;label id="ctl00_ContentPlaceHolder1_EmployeeSkillExperience-error" class="error" for="ctl00_ContentPlaceHolder1_EmployeeSkillExperience"&gt;This field is required.&lt;/label&gt;
         &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  
  
  <p>It should have been like this:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div class="form-group has-error"&gt;
     &lt;label class="col-sm-5 control-label"&gt;Experience &lt;small&gt;(in years) &lt;/small&gt;&lt;/label&gt;
     &lt;div class="col-sm-7"&gt;
            &lt;input name="ctl00$ContentPlaceHolder1$EmployeeSkillExperience" type="text" maxlength="4" id="ctl00_ContentPlaceHolder1_EmployeeSkillExperience" class="form-control" required="required" aria-required="true" aria-describedby="ctl00_ContentPlaceHolder1_EmployeeSkillExperience-error" aria-invalid="true"&gt;
           &lt;span id="ctl00_ContentPlaceHolder1_EmployeeSkillExperience-error" class="help-block"&gt;This field is required.&lt;/span&gt;
       &lt;/div&gt;
  </code></pre>
  
  <p></p>
