Modal with NavigationPage creates memory leaks

[Pastajello]

Description

Hello.

I've noticed a memory leak when user uses NavigationPage to open a modal with another NavigationPage like so:
Navigation.PushModalAsync(new NavigationPage(new MainPage()));

When we open a modal without NavigationPage there is no leakage.

I'm using AdamE.MemoryToolkit.Maui for leak detection.

IOS and Android differ slightly, Android show leaks on navigating back, iOS on navigating forward.

Steps to Reproduce

1. Open project from repo: https://github.com/Pastajello/Leak_NavigationPage
2. Run the app in Debug
3. Tap the button "Navigate": On iOS: see that leaks appear
4. Tap button "Back" : On Android see that leak appear

This MAY be fixed with #33358 but I have not tested it with the changes as there is no packagge available in PR?

I'm a bot. Here is a possible related and/or duplicate issue (I may be wrong):

• [Android] Modal page wrapped in NavigationPage is not garbage collected after PopModalAsync #34456

Oh hell I see that I created a duplicate. Yet, on my end I saw iOS issues as well so worth to check.

Ok, so for me

<PackageReference Include="Microsoft.Maui.Controls" Version="10.0.50-ci.pr33358.26158.20" />

solves the issue on Android but NOT on iOS :D
It's something ;)
