Test that postMessage doesn't block on event loop

Per spec postMessage should queue a message up on the target port immediately.

Instead, when Workers are involved, some implementations queue a task up on current thread's event loop, which means that in case it gets blocked, some messages are never sent.

Resolves https://github.com/whatwg/html/issues/5485.
