WinUI: NavigationPage transitions still animate when passing `animated: false` to PushAsync/PopAsync

[ArrowCase]

Description

When using PushAsync and PopAsync with no parameters or when passing animated: true, the page transitions animate from side to side as expected. However, when passing animated: false, a different vertical animation still occurs on Windows 10.

Steps to Reproduce

1. Create a new MAUI app
2. Replace MainPage = new AppShell() with MainPage = new NavigationPage(new MainPage()) in App.xaml.cs
3. Add a second content page and write event handlers in the code behind to allow navigating between the two pages with App.Current.MainPage.Navigation.PushAsync/PopAsync and pass animated: false to those methods.

Expected behavior: There is no transition animation, and the new page appears instantly.

Actual behavior: The new page slides up from the bottom of the screen.

Did you find any workaround?

For some reason, if the first page is removed from the navigation stack after awaiting the PushAsync call, there is no longer an animation for the transition.

Page firstPage = App.Current.MainPage.Navigation.NavigationStack[^1];
await App.Current.MainPage.Navigation.PushAsync(new SecondPage(), animated: false);
App.Current.MainPage.Navigation.RemovePage(firstPage);

Obviously, this is not a real workaround.

I have the same Issue under Android.

like: Shell.Current.GoToAsync("//sample", false);
