title: d3.select.style not working on firefox
body: <p>I just spent an embarrassing amount of time resolving this error and want to document the answer.</p>
  
  <p>The following bit of code has the desired result on Chrome but not on Firefox:</p>
  
  <pre><code>svg=d3.select('svg').style({height : 100,width : 200})
  </code></pre>
  
  <p>Why?</p>
