The following layout test is flaky on Mojave, iOS SIM WK2 imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-italic.html Probable cause: Test is very flaky, and appears to have been flaky since imported. Able to reproduce locally from the oldest version I can spade (r228049) and various versions up to and including current (r243314). Same Diff produced locally that is produced by the bots. Reproduced with: run-webkit-tests imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-italic.html --iterations 500 -f Flakiness Dashboard: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fmathml%2Frelations%2Fcss-styling%2Fmathvariant-italic.html Diff: https://build.webkit.org/results/Apple%20Mojave%20Release%20WK2%20(Tests)/r243277%20(3230)/imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-italic-diff.png

Two other layout tests from the same directory are failing as well. imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-bold.html imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-double-struck.html imported/w3c/web-platform-tests/mathml/relations/css-styling/mathvariant-italic.html Dashboard for all 3: https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fmathml%2Frelations%2Fcss-styling%2Fmathvariant-bold.html%20imported%2Fw3c%2Fweb-platform-tests%2Fmathml%2Frelations%2Fcss-styling%2Fmathvariant-double-struck.html%20imported%2Fw3c%2Fweb-platform-tests%2Fmathml%2Frelations%2Fcss-styling%2Fmathvariant-italic.html Dashboard for each tests only shows a few platforms being affected, but when attempting locally I can get it to fail on other platforms not seen on dashboard.
