Details

When bug 1473786 landed, it caused some mochitest bustage, which came with a screenshot that looks like it was taken before the first error happened:

https://taskcluster-artifacts.net/AKmGTGMpRw-746We-6XbNg/0/public/test_info/mozilla-test-fail-screenshot_Ek2PHY.png

And the logs showed this for the first test failure:

17:42:19     INFO - TEST-UNEXPECTED-FAIL | dom/canvas/test/test_imagebitmap_extensions.html | [YUV422P -> RGBA32] pixel(1,0)channnel(R): dstImageDataValue:255 should equal to dstDataValue_R: 28 
17:42:19     INFO -     window.onmessage@dom/canvas/test/test_imagebitmap_extensions.html:31:9
17:42:19     INFO -     EventHandlerNonNull*@dom/canvas/test/test_imagebitmap_extensions.html:29:5
17:42:19     INFO - Not taking screenshot here: see the one that was previously logged

So, that first screenshot, that was taken for $reason, is preventing an actual screenshot from being taken of the actual failure.

Bug 1478269 is on file for the test failure itself.
