is a flaky image diff

Reviewed by Jer Noble and Jonathan Bedard.
The test is flaky because the onplaying event handler called takeScreenshot()
immediately after pausing the video.
This results in a blank screenshot (no cue text visible) compared against the
reference that always shows the text
due to video rendering times being slower on debug and release builds under
load.
Fix in background_shorthand_css_relative_url.html: Replace takeScreenshot()
with takeScreenshotDelayed(10)
