`navigator.serviceWorker.ready` attribute must return the result of running
these steps:

1.  Let `promise` be a newly-created [promise][1].
2.  Return `promise`.
3.  Run the following steps asynchronously:
    1.  Let `registration` be the result of running [_ScopeMatch
        algorithm][2] with document's url as its argument.
    2.  If `registration` is null, then:
        1.  Wait for the document to have a matching [registration][3].
    3.  If the [registration][3], represented by `registration`, for the
        document has an [active worker][4], then:
        1.  Resolve `promise` with the [ServiceWorker][5] object associated
            with the [active worker][4].
        2.  Abort these steps.
    4.  If the [registration][3], represented by `registration`, for the
        document has a [worker in waiting][6], then:
        1.  Resolve `promise` with the [ServiceWorker][5] object associated
            with the [worker in waiting][6].
        2.  Abort these steps.
    5.  Wait until the [registration][3], represented by `registration`,
        for the document acquires a [worker in waiting][6] through a new
        [installation process][7].
    6.  Resolve `promise` with the [ServiceWorker][5] object associated
        with the [worker in waiting][6].
Note that `ready` attribute is desinged in a way that the returned [promise][1]
will never reject. Instead, it waits until the [promise][1] resolves with a
newly installed [worker in waiting][6]. Hence, the `state` of the acquired
[`ServiceWorker`][8] object is either `installed`, `activating` or `activated`.
