http/tests/contentextensions/css-display-none-after-ignore-previous-rules.html is flaky on Sierra and High Sierra Release WK2 according to the flakiness dashboard:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fcontentextensions%2Fcss-display-none-after-ignore-previous-rules.html

https://build.webkit.org/results/Apple%20High%20Sierra%20Release%20WK2%20(Tests)/r225400%20(1490)/results.html
https://build.webkit.org/builders/Apple%20High%20Sierra%20Release%20WK2%20(Tests)/builds/1490

This doesn't look to be a recent regression according to the dashboard, however the diff does seem to be similar to other content extension tests that are flaky:
