We are able to remove ServiceWorkerVisible and instead use ServiceWorkersEnabled in its place since we are no longer limiting where ServiceWorker instances are exposed. The correctness of ExtendableMessageEvent.source is addressed later in the stack. Although we enable skip-waiting-installed.https.html here, we also have to make it expected it will sometimes fail due to an inherent IPC race; bug 1926641 describes the situation.
