  // about:blank navigation synchronously.
  //
  // 1. Inserting an <iframe> into the active document with no src and no
  //    srcdoc or with src = "about:blank".
  // 2. Opening a new window with no specified URL or with URL = "about:blank".
  //
  // In both cases, Blink will initialize the new browsing context, and then
  // immediately re-navigate to "about:blank". This leads to a number of odd
  // situations throughout the navigation stack, and it is spec-incompliant.
  //
  // For a new <iframe>, the re-navigation to "about:blank" should be a regular
  // asynchronous navigation.
  //
  // For a new window, there should be no navigation at all: the standard states

  // There are two different kinds of NavigationClients, the request
  // NavigationClient and the commit NavigationClient.
  //
  // ## Request NavigationClient ##
  // Set if and only if the frame that initiated the navigation and the frame
  // being navigated are both RenderFrameImpls in the same frame tree (i.e. the
  // navigation does not ever go through a RenderFrameProxy). This has
  // interesting implications for behavior differences between the two example
  // frame trees below:
  //
  //   a.com           a.com
  //     ↓               ↓
  //   b.com       example.a.com
  //
  // Assuming the standard site-per-process allocation policy, though (a.com) is
  // cross-origin to both (b.com) and (example.a.com):
  //
  // - (a.com) performing a navigation in (b.com) *will not* create a request
  //   NavigationClient but
  // - (a.com) performing a navigation in (example.a.com) *will* create a
  //   request NavigationClient
  //
  // Note that the initiating RenderFrameImpl does *not* own the request
  // NavigationClient. Rather, the RenderFrameImpl that the navigation *targets*
  // is the RenderFrameImpl that owns the request NavigationClient.
  //
  // ## Commit NavigationClient ##
  // Always set in the RenderFrameImpl that has been selected to commit a
  // navigation. This selection happens when the NavigationRequest in the
  // browser process reaches READY_TO_COMMIT.
  //
  // If a navigation will commit in the same RenderFrameImpl that owns the
  // request NavigationClient, the request NavigationClient will be reused as
  // the commit NavigationClient. The way this works is:
  //   1.) RenderFrameHostImpl::BeginNavigation() accepts an always-bound remote
  //       to the RenderFrameImpl's `navigation_client_impl_`.
  //   2.) In `NavigationRequest::ctor()`, the request consumes the
  //       NavigationClient remote, and
  //       `NavigationRequest::SetNavigationClient()` assigns
  //       `NavigationRequest::request_navigation_client_` to it.
  //   3.) Eventually, `NavigationRequest` picks a `RenderFrameHostImpl` to
  //   commit
  //       to. In `NavigationRequest::CommitNavigation()`, the request needs to
  //       set its `commit_navigation_client_` to the `NavigationClient`
  //       implementation in the target RenderFrameImpl. If we detect that the
  //       navigation will commit to the same frame that
  //       `NavigationRequest::request_navigation_client_` points to, then the
  //       browser will reuse the request navigation client as the commit one.
  //       Otherwise, it requests a *new* client from the renderer, to act as
  //       the target RenderFrameImpl's `NavigationClient`.
  //
  // ## Navigation Cancellation ##
  // Cancellation is signalled by closing the NavigationClient message pipe.
  // This will eventually trigger a connection error in the browser process,
  // which normally invokes NavigationRequest::OnRendererAbortedNavigation().
  //
  // However, once the NavigationRequest reaches READY_TO_COMMIT in the browser
  // process, *only* the commit NavigationClient may cancel the navigation by
  // closing the message pipe. Thus, only navigations which reuse the RFH may be
  // cancelled (or more accurately, ignored) at this point.
  //
  // Unfortunately, this behavior is important for web compatibility: there are
  // sites which depend on a call to window.stop() or document.open() to cancel
  // a same-site navigation: see https://crbug.com/763106 for background.
  //
  // Note that using RenderDocument means that all cross-document navigations
  // will use a provisional RenderFrameImpl: as such, all cross-document
  // navigations with RenderDocument will ignore cancellation after
  // READY_TO_COMMIT. To handle this, all renderer-initiated navigations will
  // not enter the READY_TO_COMMIT stage until the task that initiated the
  // navigation finishes, to ensure that no renderer-initiated navigation
  // cancellation can take place after READY_TO_COMMIT. For more details, see
