Updated test expectations: https://trac.webkit.org/changeset/278205/webkit
We still have this expectation - https://searchfox.org/wubkat/rev/c67bb750f2c1083399f0dbe7d08b416cd45eee34/LayoutTests/platform/mac-wk1/TestExpectations#2262 Although WPT shows that we are passing it - https://wpt.fyi/results/css/css-contain/contain-paint-ignored-cases-ruby-stacking-and-clipping-001.html?label=experimental&label=master&aligned Should we give it another try to remove expectation and see if we can enable it without any platform specific expectation?
