1.22 +/* Test for Bug 628888 - Animations in external document sometimes don't run
1.23 + *
1.24 + * This bug concerns a condition where an external document is loaded after the
1.25 + * page show event is dispatched, leaving the external document paused.
1.26 + *
1.27 + * To reproduce the bug we attach an external document with animation after the
1.28 + * page show event has fired.
1.29 + *
1.30 + * However, it is difficult to test if the animation is playing or not since we
1.31 + * don't receive events from animations running in an external document.
1.32 + *
1.33 + * Our approach is to simply render the result to a canvas (which requires
1.34 + * elevated privileges and that is why we are using a MochiTest rather
1.35 + * than a reftest) and poll one of the pixels to see if it changes colour.
1.36 + *
1.37 + * This should mean the test succeeds quickly but fails slowly.
