🐞 Bug report

Description

Intermittently, using Chrome with geolocate enabled, calling this.geolocation$.pipe(take(1)).subscribe(position => { doesn't have anything returned from the observer

Reproduction

this.geolocation$.pipe(take(1)).subscribe(position => {
                this.latitude = position.coords.latitude;
                this.longitude = position.coords.longitude;
                console.log('a');
            }, () => {
                console.log('b');
            },
            () => {
                console.log('c');
            });

        if (!this.geolocationSupport) {
                console.log('d');
        }

None of the console logs happen

🐞 Bug report

Description

I'm working on creating a PR to upgrade package to use ng v12.

It appears that the current version of the start:ssr script is not working.

I'd like to verify it'd be OK if the PR I submit also won't fix that particular issue.

Reproduction

npm install
npm run start:ssr

🚀 Feature request

Is there a way to easily unsubscribe from Observable (geolocation service)?

When moving away from a component which uses geolocation service, I would like to stop observing the position. I couldn't find direct method to do that.

When I move back to the same component, it subscribes again and I have now two observers monitoring user position. If I do it again, I would have three observers firing at the same time with updated position.

Since I couldn't find direct solution, I used pipe with takeWhile, but it looks awkward.

🚀 Feature request

Is your feature request related to a problem?

Having GEOLOCATION_SUPPORT injection token does not quite answer the question of whether the developer can use the geolocation Web API. The GEOLOCATION_SUPPORT simply checks if navigator.geolocation object is available. However, the user may have received the browser popup during one of the previous visits to the website and automatically clicked "Block" (like many of us do these days whenever any popup shows up). In this case, the GEOLOCATION_SUPPORT will resolve to true, but geolocation$ observable will emit an error.

Describe the solution you'd like

To answer the question of whether the user has allowed the website access to geolocation, we can run the following code:

navigator.permissions.query({ name: 'geolocation' }).then((x) => console.log(x.state))
// this will print "prompt", "denied", or "granted"

I wonder if an injection token GEOLOCATION_PERMISSION could be introduced that would run the code above under the hood? Given the fact that this API returns a Promise, I'm not sure if it can still be an Injection token or if it'll have to be an observable service similar to the geolocation$

[Important] Something to keep in mind: the support for the API above is somewhat spotty: https://caniuse.com/permissions-api

Describe alternatives you've considered

Here people suggest using the second callback for the navigator.geolocation.watchPosition method that's called upon an error. This does not really solve the issue for me because calling this function will trigger the popup and I would like to know whether the geolocation Web API is available before the popup shows up.
