    <thetext>The following layout tests are flaky on MacOS Mojave

webanimations/accelerated-animation-with-delay-and-seek.html
webanimations/accelerated-animation-with-delay.html 
webanimations/accelerated-transition-by-removing-property.html

Probable cause:

These three tests are image failures that fail in tandem. these tests are failing to draw something and instead have a blank screen.

    <thetext>This looks a lot like the DRT snapshotting issue I thought we already addressed.</thetext>
