This is split from the previous changeset since if we include dom/ the file size is too large for phabricator to handle. This is an autogenerated commit to handle scripts loading mochitest harness files, in the simple case where the script src is on the same line as the tag. This was generated with https://bug1544322.bmoattachments.org/attachment.cgi?id=9058170 using the `--part 2` argument.

/* 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.
