ANR when using Clustering with 1000 items only

[spss20]

Environment details

1. maps-compose
2. Android 13
3. 4.3.3

Steps to reproduce

Load map with Clustering containing 1000 items in densed area

Code example

@OptIn(MapsComposeExperimentalApi::class)
@Composable
fun MainView(modifier: Modifier = Modifier) {
    val cameraPosition = rememberCameraPositionState {
        position = CameraPosition.fromLatLngZoom(getRandomPosition(), 9f)
    }

    val stationsList = remember {
        mutableStateListOf<StationItem>()
    }

    println("Recomposition")
    LaunchedEffect(Unit) {
        for (i in 1..1000) {
            val position = getRandomPosition();
            stationsList.add(
                StationItem(
                    position, "Marker $i",
                    "Snipper", 0f
                )
            )
        }
    }

    GoogleMap(modifier = modifier, cameraPositionState = cameraPosition) {
        Clustering(items = stationsList)
    }
}

fun getRandomPosition(): LatLng {
    return LatLng(
        28.354945 + Random.nextFloat(),
        76.948420 + Random.nextFloat()
    );
}
