I was not able to reproduce the image failure locally on iOS 14 simulator using run-webkit-tests --force --ios-simulator --iterations 100 --exit-after-n-failures 1 fast/images/image-subsampling.html. (The revision I tested was
r281967
. The failure has been seen for a while according to the history, so I should be able to reproduce with that revision if it was reproducible.)

Actual image is missing the red square. This seems almost impossible. Why would these work ctx.fillStyle = "green" ctx.fillStyle = "blue" and ctx.fillStyle = "red" right before them not work?
