    <thetext>Chromium&apos;s webkit_unit_tests started to fail since a change in bug 78549.

This affects the following two tests:
  CCOcclusionTrackerTest.surfaceOcclusionWithOverlappingSiblingSurfaces
  CCOcclusionTrackerTest.surfaceOcclusionInScreenSpace

I&apos;m going to disable these two tests for now. Please fix this.</thetext>
