The test's background color is white in the reference image and gray in the test image. Not a blocker but something is broken.

My bug 1376805 patches caused this intermittent to happen more frequently and it got backed out.
The failure open happens in Stylo-vs-Gecko mode. view-source-image.html has an iframe whose src is set to view-source:file:///home/worker/workspace/build/tests/reftest/tests/layout/reftests/view-source/blue-circle-16x16.png and that is meant to load in the same way as setting the src to .../blue-circle-16x16.png directly. (That's the aim of bug 464339, which introduced this test.)
From logging, it looks like the URL of the document at the time we make the decision to use a Gecko or Servo style backend -- when test fails or passes -- is about:neterror?e=unknownProtocolFound&u=view-source%3Afile%3A///home/worker/workspace/build/tests/reftest/tests/layout/reftests/view-source/blue-circle-16x16.png&c=&f=regular&d=Firefox%20doesn%E2%80%99t%20know%20how%20to%20open%20this%20address%2C%20because%20one%20of%20the%20following%20protocols%20%28view-source%2C%20file%29%20isn%E2%80%99t%20associated%20with%20any%20program%20or%20is%20not%20allowed%20in%20this%20context. I don't understand why it's that rather than the actual view-source: URL.
But I also don't understand why, when I open view-source-image.html locally, I don't see the blue circle in the iframe and instead just get a blank document. It works when in a top-level tab, though...

(Correction: it didn't get backed out.)

Ah, so this test is permafail in non-stylo builds. I think I'll just mark it as random-if for styloVsGecko and move on.

Mark view-source-image.html random in styloVsGecko. r=me

It's too late for 54. Mark 54 won't fix.
