title: Dotted border near checkbox IE9
body: <p>I use EXT.Js framework and i got an issue with IE9(in IE8 and previous versions all works fine): a dotted border near all checkboxes when click on it.
  I tried to set in main css file:</p>
  
  <pre><code>body.ext-ie input{
      outline: none;
  }
  </code></pre>
  
  <p>But it does not work.</p>
  
  <p>I think its about a label associeted with my checkbox, but i don't really know, how to fix it.</p>
  
  <p>An example of my issue:</p>
  
  <p><img src="https://i.stack.imgur.com/5SE5n.jpg" alt="wrong behavior in red"></p>
  
  <p>ExtJs code, that generate this checkbox is:</p>
  
  <pre><code>{
      fieldLabel: 'XXXX XXXX',    
      name: 'XXXX',                
      xtype: 'checkbox',    
      disabled: !isXXXXX}
  </code></pre>
  
  <p>A css file is available here: <a href="http://pastebin.com/VW7PLm3J" rel="nofollow noreferrer">css file</a></p>
  
  <p><strong>UPD 1</strong></p>
  
  <p>I've corrected the ExtJS file as below: JS:</p>
  
  <pre><code>items [{
      fieldLabel: 'xxx',    
      name: 'xxx',                
      xtype: 'checkbox', 
      style: {outline: 'none'}, 
      onfocus: function() {this.style.outline = "none"; }
   }]
  </code></pre>
  
  <p>it generetes the following html:</p>
  
  <pre><code>&lt;div class="x-form-check-wrap" id="ext-gen271" style="width: 180px;"&gt;
    &lt;input type="checkbox" autocomplete="off" id="ext-comp-1161" name="persistentRecoveryEnabled" class=" x-form- 
   checkbox x-form-field" style="outline: none;" checked=""&gt;
    &lt;label for="ext-comp-1161" class="x-form-cb-label" id="ext-gen272"&gt;&amp;nbsp;&lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>in a Document Mode Quirks Mode(Page default) dotted line appears around the "x-form-cb-label".</p>
  
  <p>in a Document Mode IE9 Standarts  dotted line doesn't appear with this settings.</p>
  
  <p>CSS modification doesn't help at all.</p>
  
  <p>So, there are two questions:</p>
  
  <ol>
  <li>how to set a style to the <code>class="x-form-cb-label"</code> via JS?</li>
  <li>how to set Document Mode IE9 Standarts as Page Default via JS? (html is genereted by ExtJS)</li>
  </ol>
