+     image to be ready, because there's nothing better we can do. If we fix
+     Bug 1006883, we can do away with this setTimeout.
+
+     For now, the setTimeout is just here to increase the likelihood that we
+     actually test the high-quality downscaled version of the image. If the
+     setTimeout happens to fire before the high-quality downscaled rendering is
+     ready, then this the test will pass without testing what it's trying to
+     test, which is fine as long as that's rare.  -->
