Bug 1528032 [wpt PR 15377] - WPT: service worker: Loosen postmessage-to-client-message-queue.https.html., a=testonly Automatic update from web-platform-tests WPT: service worker: Loosen postmessage-to-client-message-queue.https.html. Chrome flakily failed the test because it doesn't guarantee the order between message and fetch event. That might violate the spec, but the test doesn't need to test this. It's meant to test that the client message queue isn't enabled until a certain time. We can test that without requiring message/fetch ordering. Loosen the test to just check that the messages arrive after |earliest_dispatch|.
