MvxPagePresentationHint does not work on ios when the view being navigated to is inside a navigation controller

[calebwilson706]

🐛 Bug Report

When i use a MvxPagePresentationHint to navigate to a view in which is wrapped in a navigation controller it does not navigate to the tab for this view model

Expected behavior

It should navigate to the view model passed in with the presentation hint.

Reproduction steps

1.) Create a view controller which is wrapped in a navigation controller using the MvxTabPresentationAttribute
2.) try to navigate to this view using ChangePresentation(new MvxPagePresentationHint(YourViewModelType))

Configuration

Version: 8.0.2

Platform:

• 📱 iOS
• 🤖 Android
• 🏁 WPF
• 🌎 UWP
• 🍎 MacOS
• 📺 tvOS
• 🐒 Xamarin.Forms

from debugging i have found that inside ChangePagePresentation that GetViewModelType is returning IMxvViewModel for my view controller instead of my bespoke view model type

[calebwilson706]

However it isn't doing this for all my view controllers wrapped inside a navigation controller, it is only one of them

[calebwilson706]

Im seeing now that the ViewModel property for my view controller that i'm looking to navigate too is null and hence why it is not finding the right type. Any suggestions?
