Alert 2 emits when dismissOnTimeout and dismissible if dismissed before time out

[dafreaki]

in alert.component.ts
caused by this as it fires after a onClose has been called by the dismiss (click)="onClose()"
if (this.dismissOnTimeout) {
setTimeout(() => this.onClose(), this.dismissOnTimeout);
}

fix would be something like the following to stop the emit being sent if the alert has been closed already

onClose() {
if (!this.closed){
this.closed = true;
this.close.emit(this);
}
}
