I have the following piece of code that is triggered on a button click, everything works as expected but when the code reaches: this.router.navigateToRoute the whole browser hangs.

Can someone explain this behavior to me?

```auto
async submit() {
        var isValid = await this.isDeliveryValid();
        if(isValid)
        {
           var response = await this.createOrder();
           if(response.isCreated){
                await this.dialogService.open({
                    viewModel: MessageModal,
                    model: [
                        "Some Message",
                        response.message
                    ]
                }).whenClosed();
                this.router.navigateToRoute("emails");
           }
        }
    }

```

Emails route activate method may return a promise which never resolves causing the framework to wait indefinitely
