title: SVG not showing in Opera and Firefox, but Chrome
body: <p>I'm trying to display this simple embedded SVG image:</p>
  <pre><code>&lt;!DOCTYPE HTML&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;svg width=&quot;640&quot; height=&quot;480&quot; xmlns=&quot;http://www.w3.org/2000/svg&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot;&gt;
   &lt;!-- Created with SVG-edit - http://svg-edit.googlecode.com/ --&gt;
   &lt;g&gt;
    &lt;title&gt;Layer 1&lt;/title&gt;
    &lt;text xml:space=&quot;preserve&quot; text-anchor=&quot;middle&quot; font-family=&quot;serif&quot; font-size=&quot;24&quot; id=&quot;svg_1&quot; y=&quot;125&quot; x=&quot;141&quot; stroke-width=&quot;0&quot; stroke=&quot;#000000&quot; fill=&quot;#000000&quot;&gt;test&lt;/text&gt;
   &lt;/g&gt;
  &lt;/svg&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  <p>Chrome shows it, but Opera and Firefox don't. Is there something missing?</p>
