body: <p>When the developer console is open in chrome, why does onmouseover stop working?
  It instead fires onclick.  </p>
  
  <p>Consider this simple example.  It resizes the image onMouseOver when the console is closed, but only on click when the console is open</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;script&gt;
      function over(x) { x.style.height="64px"; }
      function out(x) {  x.style.height="32px"; }
  &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;img onmouseover="over(this)" onmouseout="out(this)" src="animage.png" /&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
