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