unmountComponentAtNode不适用于自定义呈现的组件

Question

问题是当react在根树之外渲染新组件时，我无法处理并卸载：

createInfoWindow = (e, map, place, marker) => {
    let container = 0;
    infoWindow = new window.google.maps.InfoWindow({
        content: '<div id=infoWindow />',
        position: {lat: e.latLng.lat(), lng: e.latLng.lng()},
    });
    infoWindow.addListener('domready', e => {
        ReactDOM.render(<InfoWindow
                ref={this.ref}
                desc={place.description}
                clicked={() => this.onClickHandler(place.id)}/>,
            document.getElementById('infoWindow'))
    });
    infoWindow.open(map, marker);
    // ReactDOM.unmountComponentAtNode(document.getElementById('infoWindow'))
};
