Seen on Chromium Win dbg - http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Win%20(dbg)(2)/builds/6586 The failure is reported as MISSING, but I think it's actually a TEXT failure being mis-reported due to Bug 63104. I couldn't repro locally, but it could be a bug in the test causing a JS exception, so layoutTestController.dumpAsText() is never called. The test was added in r92698. Will add TEXT and MISSING expectations for now.
