    Service workers: enable the client message queue

    A ServiceWorkerContainer object has a client message queue task source, initially disabled, which holds tasks until the client is ready to get the messages from its service worker. This patch adds a condition that enables the task source:
    * when DOMContentLoaded is dispatched
    * when a worker client has executed run a worker algorithm

    Editorial: use "active function object" more often

    In #1541, a few checks on the "currently-executing constructor" were
    added. The pull request review revealed that this phrase was not
    sufficiently precise, so it was replaced with "active function object",
    a term defined in the JavaScript specification. However, this was only
    done in one of the three places the imprecise term appears. This tidies
    up the other two.

    Be more precise about nested and discarded browsing contexts

    This commit tries to clear up some of the confusion in the current spec
    around nested and discarded browsing contexts, and how they impact the
    processing model.
    First, many of the definitions in the "nested browsing context" section
    are rephrased for clarity. Per #1180, the term "nested browsing context"
    itself becomes a field of a "browsing context container". The field has
    values of either a browsing context, or null. Then, all algorithms which
    refer to a browsing context container's nested browsing context are
    explicitly updated to account for the null case. In particular, this
    makes it clearer that when a browsing context is discarded, the
    associated browsing context container has its nested browsing context
    set to null.
    Then, we make a normative change to make window.{top, parent,
    frameElement} all return null when their associated browsing context has
    been discarded. As discussed in #1279, browser behavior here varies
    extensively, but nobody seems to follow the current spec at all, so we
    went with the 2/4 majority of returning null. A test case is at We
    add an example to the spec to make the intended behavior clear.
    We also make the normative change that documents in discarded browsing
    contexts (i.e. documents belonging to iframe windows when the iframe has
    been removed from the document) have no browsing context. This may have
    been the intention of the spec previously, but a strict reading did not
    support it. Regardless, all user agents seem to agree on this point, as
    seen by how defaultView no longer returns the WindowProxy in, and
    how fetches do not happen and script is not executed in (They
    differ in the particulars due to bugs, e.g. some return undefined when
    they should return null, and Edge seems to keep the Location object
    around and to give strange errors when accessing defaultView.)
    Along the way, this clarifies some of the garbage collection behavior
    and includes a number of editorial tweaks, notably including the
    movement of the definition of "associated Document" to the Window
    object's section, and uniformizing all references to it. (They were
    previously a hodgepodge of "associated Document", "newest Document",
    and "window's Document object".)
    Fixes #1180. Fixes #1279.

    Use only the incumbent global in postMessage

    Previously one of the origin checks was performed with the entry
    settings object, while the origin and source attributes of the resulting
    MessageEvent were derived from the incumbent settings object. At least
    WebKit and Blink appear to use the same global for both, and it makes
    sense to align the checks on the same global.
    The difference is only observable in test cases that fiddle with
    document.domain, as entry and incumbent are always same origin-domain
    (but, in document.domain cases, not always same origin).
    Fixes #1542. Helps #1431 but hurts #1430.

    Disallow mismatches between custom element local names and brands

    Without this fix, it is possible to install the brand for one type of
    element on an element with a different local name, in one of two
    different ways (both shown here as examples). This fix makes the super()
    call throw when this is attempted, preserving the invariant that a brand
    is only installed on an element with the correct local name.

    Use the associated document for pushState/replaceState's origin check

    This updates the origin check in pushState/replaceState to use the
    origin of the document of the relevant History object, instead of that
    of the entry settings object. This more correctly matches 2/3 open
    source browsers:

    Prevent double custom element constructor calls

    If creating an element failed the first time due a misbehaving
    constructor, it was possible that in the future we would try to upgrade
    the element, running the constructor again. This commit uses the
    newly-introduced (as of whatwg/dom#282) custom
    element state of "failed" to prevent upgrading such elements.

    Use the Window's associated Document for allow-modals sandbox checks

    This fixes #1206. As noted there, the previous indirections were wacky
    and unnecessary.
    Chrome and Firefox nightly implement a slightly different behavior,
    choosing the Window's browsing context's active Document, instead of the
    Window's associated Document. This can be different in edge cases as
    discussed in #1473 (comment).
    However, in Firefox they are not distinguishable, due to another
    security check that prevents these edge cases from being triggered.
    #1548 proposes to add a security check like Firefox's to the spec, which
    would obviate the difference in all cases. In the meantime, the choice
    of associated Document is more straightforward.

    Align with vocabulary changes in the DOM Standard

    This commit makes two normative changes:
    * It fixes "prepare a script" to not abort inside shadow trees.
    * It makes <img> use "connected" (though further study of <img> is probably warranted).
    It also aligns with changes in the DOM Standard that are editorial:
    * “in a document” -> “in a document tree” (instances that are still “in a document” require further investigation)
    * “in a shadow-including document” -> “is connected”
    * “node is connected” -> “becomes connected”
    * “node is disconnected” -> “becomes disconnected”
