Angular-google-maps: erro agm-snazzy-info-window na renderização

Descrição do problema
Estou tentando usar agm-snazzy-info-window sem marcador, mas recebendo erro na renderização desta janela
aqui está o código:

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

_Quais etapas devemos tentar em sua demonstração para ver o problema?_

adicione o componente de interface do usuário agm-snazzy-info-window, defina o parâmetro de entrada [isOpen]="true"

Comportamento atual

versão angular2 e angular-google-maps

    "agm/core": "1.0.0-beta.1",
    "agm/snazzy-info-window": "1.0.0-beta.1",
    "snazzy-info-window": "1.1.0",

Outra informação

Interessante pensar que quando removo o parâmetro [isOpen] do template o erro desaparece.
