19 /* Test for Bug 628888 - Animations in external document sometimes don't run
20 *
21 * This bug concerns a condition where an external document is loaded after the
22 * page show event is dispatched, leaving the external document paused.
23 *
24 * To reproduce the bug we attach an external document with animation after the
25 * page show event has fired.
26 *
27 * However, it is difficult to test if the animation is playing or not since we
28 * don't receive events from animations running in an external document.
29 *
30 * Our approach is to simply render the result to a canvas (which requires
31 * elevated privileges and that is why we are using a MochiTest rather
32 * than a reftest) and poll one of the pixels to see if it changes colour.
33 *
34 * This should mean the test succeeds quickly but fails slowly.
