See screenshot, Chrome on top, Safari at bottom. The Safari rendering looks too "lite".

This test passes on bots, and LayoutTests/svg/filters/feTile-expected.txt was last modified in 2012. I can reproduce the test rendering differently in Safari and Chrome indeed. Could you please clarify when this regressed, was there a version where it worked properly?

This is regression of 294844@main. It is related to drawing gradient with linearSRGB color space.
