Info Window - Support initial open state

Question
Regarding markers and infowindow...
If i add a marker on user map click is it possible after this event to immediately display the infowindow? Thanks

In SebmGoogleMapMarker

I believe we would need to set an attribute of the marker: showInfoWindow [true,false]

Unless I totally miss something.

`
/** @internal */
ngOnChanges(changes: { [key: string]: SimpleChange }) {
if (typeof this.latitude !== 'number' || typeof this.longitude !== 'number') {
return;
}
if (!this._markerAddedToManger) {
this._markerManager.addMarker(this);
this._markerAddedToManger = true;
this._addEventListeners();
return;
}
if (changes['latitude'] || changes['longitude']) {
this._markerManager.updateMarkerPosition(this);
}
if (changes['title']) {
this._markerManager.updateTitle(this);
}
if (changes['label']) {
this._markerManager.updateLabel(this);
}
if (changes['draggable']) {
this._markerManager.updateDraggable(this);
}
if (changes['iconUrl']) {
this._markerManager.updateIcon(this);
}

// Start enhancement
if(changes['showInfoWindow']) {
....
}
}

Additionally it would be cool to prevent more than 1 infowindow open at once....
