When using Shell's TabBar, navigated page are unmounted on tab switching

[nomurayoshuak]

Describe the bug & To Reproduce I am using the following Shell setup in MainPage. Within HomePage, I navigate to a lower-level page (like Page6, which is not included in the tabs). When I switch to another tab (e.g., Tab2 or Tab3) and then return to the Home tab, Page6 remains visible, but the Page6 component is unmounted, causing any buttons or other elements on Page6 to become completely non-functional.

I believe that unmounting the component at this timing is a bug. I am currently facing this issue in an ongoing project, and I would greatly appreciate your assistance in resolving it. Thank you.

// MainPage
public override VisualNode Render()
    => Window(
        Shell(
            TabBar(
                ShellContent("Home")
                    .Icon(/* icon */)
                    .RenderContent(() => new HomePage()),
                ShellContent("Tab2")
                    .Icon(/* icon */)
                    .RenderContent(() => new Page2()),
                ShellContent("Tab3")
                    .Icon(/* icon */)
                    .RenderContent(() => new Page3()),
                ShellContent("Tab4")
                    .Icon(/* icon */)
                    .RenderContent(() => new Page4()),
                ShellContent("Tab5")
                    .Icon(/* icon */)
                    .RenderContent(() => new Page5())
            )
            .Route("mainpage")
    )
);

// Navigation in the HomePage
await Navigation.PushAsync<Page6>(new Page6());
