title: Chrome getComputedStyle() returns wrong RGBA color?
body: <ol>
  <li>I set an rgba() bg-color in Chrome (Win7, 19.0.1084.56)</li>
  <li>I get the background-color with window.getComputedStyle(), &amp; <strong>it is different</strong></li>
  <li>I set the retrieved value on a new element</li>
  <li>I retrieve it again, <strong>its different again</strong></li>
  </ol>
  
  <p>Here is a fiddle: <a href="http://jsfiddle.net/zupa/KsuMp/">http://jsfiddle.net/zupa/KsuMp/</a></p>
  
  <p>In my case, the first 4 blocks have the following contents in Chrome:</p>
  
  <ul>
  <li>bg-color: rgba(255, 0, 0, 0.503906)</li>
  <li>bg-color: rgba(255, 0, 0, 0.5)</li>
  <li>bg-color: rgba(255, 0, 0, 0.496094)</li>
  <li>bg-color: rgba(255, 0, 0, 0.496094)</li>
  </ul>
  
  <p>In Firefox, I get constant rgba(255, 0, 0, 0.506)</p>
  
  <p>So, this seems to be a bug. Can you prove me wrong or suggest a workaround? I need the color for a wysiwyg editor and this is killing my unit tests.</p>
