           Summary: CORS enabled data:URL images fail to load
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.9
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: stefankienzle.de at gmail.com


Steps to reproduce the problem:
I want to load CORS enabled data:URL images (in JS or HTML) - both cases are failing.
JS:
var img = document.createElement('img');
img.onload = function () {
 ...
};
img.crossOrigin = '';
img.src = <data-url>;

HTML:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAB4AAAAeCAMAAAAM7l6QAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAAlQTFRFa2tr3Nzc////HKA8dAAAAD9JREFUeNpiYCAAmMCAkQkrTaQ0DkAdaZx2AxmMQAAmYUwmGDmoXU6ZNCPCl5jkoHY5ZU4jyt+D0uV4DQcIMADuxwY6Y1aBvAAAAABJRU5ErkJggg==" crossorigin />

Open this jsfiddle: http://jsfiddle.net/Kienz/Dv3Eu/ 
You should see three w3c images!

What is the expected behavior?
Images should be loaded.

What went wrong?
The images don't load and you got the following error in dev console:
Cross-origin image load denied by Cross-Origin Resource Sharing policy.

In Safari 5.1 (Windows 7) it works. Safari 7 (Mac OS 10.9) it fails.
