Previously, the document was shown as soon as the HTML was received, but before
the embedded components were ready (e.g. downloaded and instantiated). This
caused FOUC (Flash Of Uninstantiated Components).
This commit fixes it by preparing the new document in an off-DOM node and
swapping the nodes when the embedded components are ready.

Using `display: none` on the `<h1>` causes `innerText` to not work as expected
and include the icon ligature (`link`) in the title. This caused the window
title on the angular.io Home page to appear as "Angular - link".
This commit fixes it by not generating anchors at all for headings with the
`no-anchor` class.
Fixes#20427
PR Close#20440
The window title is derived based on the current document's `<h1>` heading. Such
headings may contain hidden/non-visible content (e.g. textual name of font
ligatures: `<i class="material-icons">link</i>`) that should not be included in
the title.
This commit fixes this by using `innerText` (instead of `textContent`) to
extract the visible text from the `<h1>` heading. It will still fall back to
`textContent` on browsers that do not support `innerText` (e.g. Firefox 44).
Fixes#17732
By reflex we began all component tests with an async `beforeEach` that called `compileComponents`.
In at least one case (`live-example.component.spec.ts`) that led to the `it` tests being async as well.
There is no need to call `.compileComponents` because CLI web pack + plugin inlines all templates and styles.
While `.compileComponents` was harmless, it added complexity and distraction which we should not inflict on future readers and testers.
Dgeni is now providing the `id` for all the documents to be viewed. So we
no longer need to add this to the DocumentContents object.
There are some notable changes in the refactoring:
`DocumentService`:
* The id of the document to render is now obtained from `LocationService.path()`.
* The `getFileNotFoundDoc` and `getErrorDoc` methods have been extracted from
the `fetchDocument` method.
`AppComponent`:
* the `pageId` is now computed in a separate `setPageId` method.
`AppComponen` spec file:
* The `TestHttp` has had the hard coded documents removed and replaced with
a function that will generate docs as needed.
Previously, the `AppComponent.pageId` was set via the current URL, rather than
the document being displayed. This is only really noticeable when the URL does not
match a valid doc and we are actually displaying a 404 page.
Now we compute the `pageId` from the URL of the document being viewed,
which is returned from the `DocumentService.currentDocument` observable instead.
