A couple important things to note about the behavior:
* The component is destroyed, meaning that all of its members will be destroyed as well, including any subscriptions to the route params
* This _does not_ mean that any `finalize` operators or `complete` on the subscription is called. This only happens if the source completes or you unsubscribe from the subscription. The documentation doesn't state that the `Router` will do this, though I can still understand why the behavior is confusing.
You can play around with these scenarios here:
https://stackblitz.com/edit/rxjs-hmpizx
* `complete` the source without unsubscribe: `next`, `complete` and `finalize` are all called, even when `complete` is called before the `next` from the `delay`
* `unsubscribe` from subscription without `complete` on the source: `finalize` happens, but the `complete` of the subscription does not, and neither does `next`
So even if the `Router` were to call `complete` on all of the `Observables` on an `ActivatedRoute`, you would see that any subscriptions with a `delay` operator would still get called.

The latest SW app version knows that `/devtools` should be redirected to
`/guide/devtools`. However, if a user has an older app version installed
(and until the SW downloads the latest version) they will get a 404 when
navigating to `/devtools`.
The reason is that the SW will see `/devtools` as a regular navigation
URL and serve `index.html` instead. The Angular app will then try to get
the content for `/devtools` by fetching `/generated/docs/devtools.json`
(which does not exist).
This commit fixes the issue by redirecting
`/generated/docs/devtools.json` to
`/geenrated/docs/guide/devtools.json`. When a user visits `/devtools`
for the first time, they will still be able to see the guide content
(while the SW updates in the background). On subsequent visits (once the
SW has downloaded the latest app version), they will be redirected to
`/guide/devtools`).
At a later time, once we are confident that the majority of users will
have updated to a newer app version, we can remove this temporary
redirect.

This fixes an issue in part 5 of the Tour of Heroes tutorial on
angular.io. At the end of the `Add RouterOutlet` section, the reader navigates to
`"/heroes"`. The next section, `Add a navigation link`, instructs the user to click ona link on the dashboard page to navigate to the heroes page. This is problematic because the previous section instructed the reader to navigate to the heroes page, not the dashboard. It assumes, the reader is on the dashboard page.

Since #41625, `/guide/updating-to-version-10` is being redirected to
`https://v11.angular.io/guide/updating-to-version-11`. However,
`v11.angular.io` itself is being redirected to `angular.io`, while v11
is the latest stable version. As a result,
`/guide/updating-to-version-10` ends up being redirected to
`https://angular.io/guide/updating-to-version-11`. Currently, this
causes a CI failure in the `aio_monidoting` job ([example failure][1]).
This will change once v12 is released as the new stable version.
Alternatively, we could update the config and tests to expected
`/guide/updating-to-version-10` to be redirected to
`https://angular.io/guide/updating-to-version-11`, but that would end up
being redirected to `https://angular.io/guide/updating-to-version-12`
once v12 would be released, which is different behavior.
This commit provides a way to test for redirects when the destination
URL is itself redirected to a different URL. This allows us to use the
intended URL (for example, `https://v11.angular.io/...`), which will
continue to work as expected regardless of what is the latest stable
version without causing CI failures.

This seems confusing and inconsistent. Either all URLs should redirect
to the latest update guide (currently `/guide/updating-to-version-12`)
or each URL should redirect to the corresponding version.
This commit implements the second approach:
- `/guide/updating-to-version-10` --> `https://v10.angular.io/guide/updating-to-version-10`

In #41788, logic was added to disambiguate case-insensitively equal docs
paths/URLs. This process includes appending a `-\d+` suffix to some
paths/URLs (for example, `/.../inject-1`). Unfortunately, some of the
Firebase redirects configured in `firebase.json` would match these URLs
and redirect them to non-existing paths.
Example failures: [stable][1], [next][2]
NOTE:
This was not picked up in the regular CI tests run for PRs, because the
local devserver and the preview server used to test PRs do not support
Firebase-like redirects.
This commit fixes this by ensuring these disambiguated paths/URLs are
not matched by the redirect rules by checking whether the part of the
suffix after the `-` contains any numeric digits. While this check is
not ideal, it should be good enough for our purpose, since the legacy
URLs that we do want to redirect contain suffixes such as `-class`,
`-function` and thus no numeric digits.

In ##41788, the `disambiguateDocsPathsProcessor` was introduced to fix
an issue with case-insensitively equal paths. This processor may alter
the paths of some docs and thus their final URL in the app.
Previously, both the `disambiguateDocPathsProcessor` and the
`createSitemap` processor (which relies on the docs' computed paths to
generate the sitemap file) were configured to run before the
"rendering-docs" phase. However, this resulted in the
`disambiguateDocPathsProcessor`'s running after `createSitemap`, which
meant that the sitemap did not include the updated doc paths.
This commit fixes it by ensuring that the
`disambiguateDocPathsProcessor` is explicitly run before the
`createSitemap` processor, so that the latter will be able to take into
account any changes made by the former.
