The following layout test is failing on Win fast/css/font-face-implicit-local-font.html fast/css/font-face-unicode-range.html fast/css/font-face-descending-unicode-range.html fast/css/font-face-download-error.html These tests depends on implicit font family replacement in FontCache. I think we should update these tests to fix https://bugs.webkit.org/show_bug.cgi?id=100446. I'm going to add suppression at this moment.
Also seems to affect svg/custom/font-face-simple.svg on Windows (suppressed).
Added ImageOnlyFailure to fast/css/font-face-unicode-range.html to silence the chromium win bot. http://trac.webkit.org/changeset/139425
