react-map-gl Marker is moving when zooming the map

I've built a React app with a map component which renders a map. I tried to add a marker, but the marker keeps moving when I zoom. What is causing this to happen?

import MapGL, { Marker } from "react-map-gl"
import { useState } from "react";

const Map = () => {
    const [viewState, setViewState] = useState({
        longitude: 4.895168,
        latitude: 52.370216,
        zoom: 10,
    })
    const [marker] = useState({
        longitude: 4.895168,
        latitude: 52.370216,
    })

    return (
        <div className="map">
            <MapGL
                {...viewState}
                style={{ width: "100%", height: "100%" }}
                mapStyle="mapbox://styles/mapbox/streets-v9"
                onMove={(evt) => setViewState(evt.viewState)}
                mapboxAccessToken="my_token"
            >
                <Marker
                    {...marker}
                />
            </MapGL>
        </div>
    )
}

export default Map;
