<pre>Hi all,
these steps can be followed to reproduce the bug:
1. Create a "video" element, a "canvas" element and its 2d "context".
2. Have the video element's "src" be a "MediaSource" URL (createObjectURL is called for a new MediaSource object).
3. Draw an image with context.drawImage(video, 0, 0);
4. You will not be able to call canvas.toDataURL, because a security exception will be raised (incorrectly).
