There is no debouncing when we store the scroll Position.
Currently, we have a message in the console after a while:

These icons are part of the app shell and used on every load (on both
desktop and mobile). Inlining them ensures they are rendered asap.

The `Logger.error()` method now only accepts a single `Error` parameter
and passes this through to the error handler.
This allows the error handler to serialize the error more accurately.
The various places that use `Logger.error()` have been updated.

The previous approach just removed the first `a` tag that
was found, but now that the header-link anchor is not at
the start of the heading, it could fail.

We have a number of observables that have `catch` handlers to recover
from errors without causing the stream to close, and breaking the app.
We also have some `try ... catch` blocks for synchronous code for a
similar reason.
In these cases we conventionally then call `logger.error` in the catch
handler. We are interested in these errors so we are going to capture them
by reporting them to Google Analytics via the new `ReportingErrorHandler`.
PR Close#22011
This is a basic implementation of error logging using the limited
facilities provided by Google Analytics.
Errors within the Angular app itself will be handled by a new
`ReportingErrorHandler` service, which overrides and extends the
built-in `ErrorHandler`.
Further, errors outside the app, which arrive at `window.onerror`
will also be reported to Google Analytics.

Apparently Object.keys on NamedNodeMap work differently with googlebot :-(
There are not tests since we don't have a way to write tests for googlebot,
but I did manually verify that after this fix googlebot correctly renders
several of the previously broken pages.

all the non-npm changes were made by the angular-material-prefix-updater tool.
the tool missed a few things, which I'll fix in a separate commit to preserve the diff.

The GaService and the E2E specs were unnecessarily complicated and had
arbitrary async timeouts to ensure that the interplay between the GA
library code and the rest of the app worked correctly. This resulted
in potential flaky tests if the timeouts were not adequate; this was
experienced when Travis upgraded to Chrome 62.
The new approach is to block loading of the Analytics library altogether
if there is a `__e2e__` flag set in the `SessionStorage` of the browser.
It doesn't appear to be enough just to set the flag directly on the
window. I think this is because the window gets cleaned when navigation
occurs (but I am not certain).
The downside of this is that we had to add a small piece of extra logic
to the GA snippet in index.html; and we also had to switch from using
`<script async ...>` to a programmatic approach to loading the GA library
which prevents the browser from eagerly fetching the library. This may
be mitigated by adding it to the HTTP/2 push configuration of the Firebase
hosting.

Previouly, whenever a new ServiceWorker update was detected the user was
prompted to update (with a notification). This turned out to be more distracting
than helpful. Also, one would get notifications on all open browser tabs/windows
and had to manually reload each one in order for the whole content (including
the app) to be updated.
This commit changes the update strategy as follows:
- Whenever a new update is detected, it is immediately activated (and all
tabs/windows will be notified).
- Once an update is activated (regardless of whether the activation was
initiated by the current tab/window or not), a flag will be set to do a
"full page navigation" the next time the user navigates to a document.
Benefits:
- All tabs/windows are updated asap.
- The updates are applied authomatically, without the user's needing to do
anything.
- The updates are applied in a way that:
a. Ensures that the app and content versions are always compatible.
b. Does not distract the user from their usual workflow.
NOTE:
The "full page navigation" may cause a flash (while the page is loading from
scratch), but this is expected to be minimal, since at that point almost all
necessary resources are cached by and served from the ServiceWorker.

`innerText` is not supported in Firefox prior to v45. In most cases (at least
the ones we are interested in), `innerText` and `textContent` work equally well,
but `textContent` is more performant (as it doesn't require a reflow).
From [MDN][1] on the differences of `innerText` vs `textContent`:
> - [...]
> - `innerText` is aware of style and will not return the text of hidden
> elements, whereas `textContent` will.
> - As `innerText` is aware of CSS styling, it will trigger a reflow, whereas
> `textContent` will not.
> - [...]
