The following layout test is flaky on macOS WK2

http/tests/workers/service/basic-unregister-then-register-again-reuse.html

Probable cause:

This seems to have recently started. The change in https://trac.webkit.org/changeset/227275/webkit is related via service workers, however it doesn't seem to be a cause.
