title: Html select option selected does not work
body: <p>How to set default selected element in combobox? Neither of the following worked for me:</p>
  
  <p>Version 3:</p>
  
  <pre><code>&lt;select id="parent"&gt;
      &lt;option value='null'&gt;(Root)&lt;/option&gt;
      &lt;option selected='yes' value='/'&gt;Main&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Version 2:</p>
  
  <pre><code>&lt;select id="parent"&gt;
      &lt;option value='null'&gt;(Root)&lt;/option&gt;
      &lt;option selected='true' value='/'&gt;Main&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Version 1:</p>
  
  <pre><code>&lt;select id="parent"&gt;
      &lt;option value='null'&gt;(Root)&lt;/option&gt;
      &lt;option selected value='/'&gt;Main&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>In all cases first option is selected on page, not that one which is marked selected.</p>
  
  <p><strong>SOME OTHER DETAILS</strong></p>
  
  <p>(1)</p>
  
  <p>Page source beginning follows:</p>
  
  <pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt;
          ...
  </code></pre>
