Angular-google-maps: 렌더링 시 agm-snazzy-info-window 오류

문제 설명
마커 없이 agm-snazzy-info-window를 사용하려고 하는데 이 창을 렌더링할 때 오류가 발생합니다.
다음은 코드입니다.

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

_데모에서 문제를 확인하려면 어떤 단계를 시도해야 합니까?_

agm-snazzy-info-window UI 구성 요소 추가, 입력 매개변수 설정 [isOpen]="true"
