[BUG] hide/show advanced markers does not work

#### Environment details

I am using the beta channel of Google Maps and `@googlemaps/markerclusterer` at 2.1.3

I am adding a bunch of marker to a clusterer:

```js
for (const launch of this.launches) {
markers.push(
new google.maps.marker.AdvancedMarkerElement({
position: { lat: launch.lat, lng: launch.lon },
title: launch.title,
}),
);
}
this.clusterer.addMarkers(markers);
this.clusterer.setMap(this.map);
```

At this point everything works fine.

Then I hide the markers:

```js
this.clusterer.setMap(null);
```

After that all the markers are hidden as expected

Then I want to show the markers again:

```js
this.clusterer.setMap(this.map);
this.clusterer.render(); // calling that makes no difference
```

That has no effect.
I would effect the marker the show after this call.
But I have to zoom (either in on out) for the marker to re-appear.

I would be up to create a repro if you have a starter template - all the GMaps starters for the JS API website seem to have an issue with the API key.
