[BUG] Popup Service - Can't access view model

[sikemullivan]

Is there an existing issue for this?

• I have searched the existing issues

Did you read the "Reporting a bug" section on Contributing file?

Current Behavior

When launching a popup using the PopupService, you used to be able to send in a lambda to setup the view model that is going to be bound.

     var result = await _popupService.ShowPopupAsync((MySelectorViewModel vm) =>
            {
                vm.Selected = selected;
                vm.Items = allItems;
            });

I feel like this can no longer be done. I have no way to access the popup's View Model.

Expected Behavior

I expect that I have a way to setup the view model when launching a popup.

Steps To Reproduce

1. Write an app one year ago that uses the Community Toolkit Popup Service
2. Upgrade the Community Toolkit
3. Experience breaking changes that are not very clear how to resolve

@sikemullivan is this still relevant? I am trying to figure out why you do not pass to constructor or aftering calling new PopUp() ... why you do not access a public variable of this PopUp which can also be a PopUp ViewModel?
