ProgressBar seems to be broken

[Dreamescaper]

Set the following MainPage:

            MainPage = new ContentPage
            {
                Content = new VerticalStackLayout()
                {
                    Children =
                    {
                        new AlohaKit.Controls.ProgressBar()
                    }
                }
            };

Expected result:
Lonely page with a ProgressBar.

Actual result:

System.ArgumentException: 'Unable to find IAnimationManager for 'AlohaKit.Controls.ProgressBar'. (Parameter 'animatable')'
