Automatic update from web-platform-tests Address concerns about CSSStyleSheet-constructable-concat.html See [1] for comments, but this CL adds reftest-wait to ensure the test finishes before the image capture, and adds PASS lines for all passed tests. This makes no difference in Chromium, but ensures this test works correctly in other browsers.
