Rg.Plugins.Popup: PopupNavigation.PushAsync does not work with XF2.5

I have the following method in my PCL:

Device.BeginInvokeOnMainThread(async () =>
{
   await PopupNavigation.PushAsync(popUpPage);
});

and have recently upgraded to the latest Xamarin.Forms 2.5.0 stable

and the method above never returns when pushing a new page with latest version.

Worked fine with previous stable Xamarin.Forms

I’m guessing it has something to do with this method: https://github.com/rotorgames/Rg.Plugins.Popup/blob/a44ace31c5b9dfa2df2cb7b1eb3200cf17e41d43/src/Rg.Plugins.Popup/Services/PopupNavigation.cs#L28
