There are severals wpt tests with high intermittent fail rate, and the reason is that there are some pixels with really small color difference. eg (255,255,255) v.s. (255,254,254). As we're lacking of `fuzzy` feature on wpt now (which will be implemented in bug1478472), we have no way to avoid these affordable differences. Therefore, I'm goint to disable those tests until we've `fuzzy` on wpt, and will re-enable them afterward.
