The following two LayoutTests are flaky failures on iOS and macOS WK2:

http/tests/workers/service/client-added-to-clients-when-restored-from-page-cache.html   
http/tests/workers/service/client-removed-from-clients-while-in-page-cache.html

https://build.webkit.org/results/Apple%20Sierra%20Debug%20WK2%20(Tests)/r229663%20(5649)/results.html

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fworkers%2Fservice%2Fclient


Both tests fail with a similar diff:
