We do have some modifications during the import process for other purposes, we're trying to minimize/stop doing so, but nothing for anti-alias even today. I don't know about Edge and WebKit, the result of the test harness is from contributors in Japan running them manually. So to me, it is only Gecko that is hitting the anti-alias issue. Even for Gecko, IIUC, setting a flag to run test properly is different from running "modified versions of the tests". I'm not very familiar but AFAIU, Blink uses some flags for CSS2 test suites too. Several factors such as UA stylesheets, system settings, fonts in the platform, anti-aliases, etc. are obstacles to run tests in a stable manner. Better to normalize them when running tests. Does this feel you good? /koji
