r118612 added fast/layers/clip-rects-assertion-expected.txt This test calls layoutTestController.dumpAsText(true); but no pixel result has been provided. Chromium fails this test as it doesn't find any baseline for the image. From the ChangeLog there, looks like we can ensure that with just the text and no image.
