The seven fast/inline/hidpi-outline-auto tests have a blank expected image, fast/css/paint-order-shadow.html has a blank actual image, and fast/forms/ios/focus-ring-size.html has both an expected and actual image. REPRODUCTION STEPS I can reproduce this on r294452, but unable to reproduce it on r294451 or earlier.
