I'm getting a strange exception on when trying to change the text of a ToolbarItem within a ContentPage on Android. This happens when the content page is hosted within a navigation page, and the navigation page itself is within a tabbed page.
When the user navigates between the tabs, then comes back & performs an action that results in the toolbar item's text being changed the following exception occurs:
Cannot access a disposed object.
Object name: 'Xamarin.Forms.Platform.Android.AppCompat.NavigationPageRenderer'.
Full stack trace attached.
App to reproduce is here: https://github.com/codemillmatt/droidcrash
1. Navigate between tabs
2. Click on one of the toolbar buttons on first tab
