title: Setting img src to a data url via work does not work in IE8?
body: <p>When I <a href="http://phrogz.net/tmp/img_via_dataurl.html" rel="nofollow noreferrer">attempt to set an image to use a data url</a> via JavaScript <em>(from <a href="https://stackoverflow.com/questions/4776670/should-setting-an-image-src-to-dataurl-be-available-immediately">this question</a>)</em>, it does not appear to work in IE8.</p>
  
  <p>The page in that first link has: <code>&lt;img id="foo" src="alphaball.png"&gt;</code><br>
  On line 25, this JavaScript code executes: <code>document.getElementById('foo').src = img_src;</code></p>
  
  <p>On all other browsers (including IE9b) this successfully changes the image from the alphaball to a picture of my head. On IE8, I see the alphaball very briefly, and then it is replaced with a missing image icon.</p>
  
  <p>Is this a known issue? Is there a workaround for using data urls with IE8 and JavaScript?</p>
