NavigationPage and FlyoutPage both call OnNavigatedTo, so it is called twice #23902
Description
Description
When navigating to a new page by assigning a new NavigationPage to the FlyoutPage's Detail property, I see NavigationPage called twice on the NavigationPage's inner page. This behavior is incorrect. OnNavigatedTo should only be called once.
First:
