    <thetext>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

    <thetext>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:

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.</thetext>
