Description:
css3/filters/effect-grayscale.html

Is a constant image failure on macOS ToT and since 272891@main.

This issue can be bisected to 272891@main using command:
run-webkit-tests --release --iterations=1 -1 css3/filters/effect-grayscale.html

Test Run:
https://build.webkit.org/#/builders/931/builds/1764/steps/13/logs/stdio
14:03:57.550 92105 worker/16 css3/filters/effect-grayscale.html allowed fuzziness {'max_difference': [0, 48], 'total_pixels': [0, 32633]}, actual difference {'max_difference': 3, 'total_pixels': 59700}: pass False
14:03:57.553 92105 [4694/70409] css3/filters/effect-grayscale.html failed unexpectedly (reference mismatch maxDifference=3; totalPixels=59700)
14:03:57.553 92105 worker/16 css3/filters/effect-grayscale.html failed:

272891@main changed pixel tolerance, but it looks like the pixel tolerance needs to be bumped more.
