title: Odd Firebug behavior with radio button
body: <p>The following is a very minor problem, I would just like to understand why this happens.</p>
  
  <p>Create a html document that looks like this:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;&lt;/title&gt;
      &lt;style&gt;
          body {font-family: Arial;}
      &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;input type="radio" name="radio" /&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Now open it in Firefox (I am using build 14.0.1) and right click the radio button to open a context menu.  From that menu select "Inspect Element with Firebug...", which will open Firebug with the HTML tab open and the radio button HTML code highlighted.</p>
  
  <p>Now try and select the radio button.  It will be selected for a second but then it quickly deselects itself. Why?</p>
  
  <p>I know if I remove that body style definition the above behavior will not happen or if I am in a different tab while Firebug is open (such as the "Console" tab) it won't happen or if Firebug isn't open it won't happen.</p>
  
  <p>I know this is super minor and very situational I just like to at least have some idea of why this is.</p>
