title: Rails: image_tag and usemap not playing nice with Firefox
body: <p>I'm using the following code to load an image and associated image map:</p>
  
  <pre><code>&lt;span&gt;&lt;%= image_tag bookcase.image_url.to_s, :usemap =&gt; "#shelfmap" %&gt;&lt;/span&gt;
  &lt;map name="#shelfmap"&gt;
    &lt;area shape="rect" coords="0,0,500,100" href="\" alt="test" /&gt;
  &lt;/map&gt;
  </code></pre>
  
  <p>The image map loads in Google Chrome, but for some reason it doesn't display in Firefox. I checked the source code and the image does have a usemap parameter set to "#shelfmap". I'm not sure what else could be the problem.</p>
