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.

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.
> - [...]

Previously, we always assumed that elements would be scrolled to the top of the
page, when calling `element.scrollIntoView()`. This is not true for elements
that cannot be scrolled to the top, e.g. when the viewport height is larger than
the height of the content after the element (common for small sections near the
end of the page).
In such cases, we would unnecessarily scroll up to account for the static
toolbar, which was unnecessary (since the element was not behind the toolbar
anyway) and caused ScrollSpy to fail to identify the scrolled-to section as
active.
This commit fixes it by ensuring that we do not scroll more than necessary in
order to align the top of the element with the bottom of the toolbar.
Fixes#17452
Previously, the top-bar's height wasn't taken into account when scrolling an
element into view. As a result, the element would be hidden behind the top-bar.
Taking the top-bar height into account was not necessary before #17155, because
the top-bar was not fixed (i.e. it scrolled away).
This commit fixes the scrolling behavior by accounting for the top-bar's height
when scrolling an element into view.
(This partially reverts #17102.)
Fixes#17219Fixes#17226
Previously, the `#top-of-page` element (used when scrolling to top) was placed
inside the content section (which at the time had zero top margin and padding).
Furthermore, there was a top offset applied when scrolling that took the static
top bar's height into account. Since now the top bar is not static any more and
the content section has a non-zero top padding, scrolling to top does not work
as expected.
This commit fixes this by:
- Moving the `#top-of-page` element to the top of the `aio-shell`.
- Stop accounting for the top bar's top.

* refactor(aio): use explicit CSS class for TOC container
This makes the styling less fragile to changes in the HTML
* fix(aio): schedule TocComponent.activeIndex updates via AsapScheduler
We use the `asap` scheduler because updates to `activeItemIndex` are triggered by DOM changes,
which, in turn, are caused by the rendering that happened due to a ChangeDetection.
Without asap, we would be updating the model while still in a ChangeDetection handler,
which is disallowed by Angular.

The side nav and menu buttons need to appear early on in the loading of the page.
Currently we are using icon fonts with ligatures to get icons for these areas.
This can result in a flash of unstyled font.
By replacing these with SVG icons, we get a better user experience.
By overriding the `MdIconRegistry` we can inline the SVG source, which
means that there will never by a delay in rendering the icons.
The new `CustomMdIconRegistry` expects a multi-provider containing an array
of `SvgIconInfo` objects. These objects hold the name and SVG source of the
icon. When `MdIconComponent` requests an SVG icon we will get it from the
pre-loading cache, if available, before delegating back to the original
`MdIconRegistry`.
Note that SVG versions of `md-icon` do not apply the `material-icons` CSS
class to the element, so the styling for the icons that we are preloading
has been changed to use `.mat-icon` instead.
Closes#16100
Previously, the path returned by `LocationService.path()` preserved leading
slashes, which resulted in requests with consequtive slashes in the URL. Such
requests would fail (with a 404) on staging.
This commit fixes it, by removing leading slashes from the path. It also
refactors `LocationService` a bit, converting path to an observable,
`currentPath` (similar to `currentUrl`), and applies certain clean-ups (e.g.
stripping slashes, query, hash) in one place, which simplifies consumption.
Closes#16230
