title: Chrome rendering issue. Fixed position anchor with UL in body
body: <p>There is a rendering issue with Google Chrome and Opera (why?=) with such code:</p>
  
  <pre><code>&lt;html&gt;
  &lt;style&gt;
      #content {
          width: 150px;
          background: gray;
      }
  
      #sidebar {
          position: fixed;
          left: 200px;
          background: gray;
      }
  &lt;/style&gt;
  &lt;body&gt;
      &lt;div id="sidebar"&gt;
          &lt;a href="#s1"&gt;Link #1&lt;/a&gt;&lt;br/&gt;
          &lt;a href="#s2"&gt;Link #2&lt;/a&gt;
      &lt;/div&gt;
  
      &lt;div id="content"&gt;
          &lt;div id="s1"&gt;
              &lt;a href="#s1"&gt;Link #1 TARGET&lt;/a&gt;

          &lt;div id="s2"&gt;
              &lt;a href="#s2"&gt;Link #2 TARGET&lt;/a&gt;
              &lt;ul&gt;
                  &lt;li&gt;Item 1&lt;/li&gt;
                  &lt;li&gt;Item 2&lt;/li&gt;
              &lt;/ul&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  
      &lt;a href="#"&gt;TOP&lt;/a&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>As you can see, I am trying to make sidebar static on the right side.
  Everything works fine, until you add some <code>&lt;UL&gt;</code> tag on the page:</p>
  
  <p><a href="http://www.youtube.com/watch?v=zkhH6di2M0c">http://www.youtube.com/watch?v=zkhH6di2M0c</a></p>
  
  <p>The fixed div sometimes starts to disappear when I click anchor links.</p>
  
  <p>What can be done to avoid such behavior?</p>
