Exception in InitializeComponent() Application's method

[Miamy]

In my test module I have:

     [SetUp]
     public void Setup()
     {
            MockForms.Init();
            Application.Current = new App();
     }

and in App.xaml.cs I have:

     protected override async void OnInitialized()
        {
            InitializeComponent(); <-- Exception throws here
           ...
        }

During executing the exception is raised:
An unhandled exception of type 'System.FieldAccessException' occurred in System.Private.CoreLib.dll
Attempt by method 'MyApp.App.InitializeComponent()' to access field 'Xamarin.Forms.FontElement.FontFamilyProperty

I'm using XF 5.0.0.2337 and Xamarin.Forms.Mocks 4.7.0.1. The Prism fraimwork is used (I don't know if this is important)

Are you able to make an example test that fails in the same way?

We could add one to the tests here:

Unfortunately, I couldn't reproduce this issue on the test project. Maybe, it caused by some third-party package. I'll let you know if some new info will appear.
