Angular-google-maps: error de agm-snazzy-info-window al renderizar

Descripcion del problema
Estoy tratando de usar agm-snazzy-info-window sin marcador, pero obtengo un error al mostrar esta ventana
aquí está el código:

<div *ngIf="selectedMarker" >
    <agm-snazzy-info-window 
         [latitude]="selectedMarker.latitude" 
         [longitude]="selectedMarker.longitude"
         [isOpen]="true">
      {{selectedMarker.id}}
    </agm-snazzy-info-window>
</div>

_¿Qué pasos deberíamos probar en su demo para ver el problema?_

agregue el componente de interfaz de usuario agm-snazzy-info-window, establezca el parámetro de entrada [isOpen]="true"

Es interesante pensar que cuando elimino el parámetro [isOpen] de la plantilla, el error desaparece.
