It might just not be loading the iframe in time for the pixel capture.

I can't repro this locally; is there anything special about LayoutTests/fast that I should consider in looking into this?

I would consider adding <link rel=preload ...> to the start of the test to load the image ahead of time.

I see failures locally with --repeat 100.

D'oh, I either didn't do enough repeats, or I forgot to remove the line from TestExpectations.

Turns out the preload doesn't go in the main html file but inside what's set for the iframe's innerHTML. Uploaded https://codereview.chromium.org/2808013003 for review.

Deflake background-image-relative-url-in-iframe.html

Deflake LayoutTests/fast/backgrounds/ test
background-image-relative-url-in-iframe.html by delaying testRunner
completion until iframe load event fires.

iframe.contentDocument.body.innerHTML has been replaced with
iframe.srcdoc in order to cause the load event to retrigger.
