[MAUI 10] Layout breaks on first navigation (Shell // route) until soft keyboard appears/disappears (Android + iOS)

[v283]

Description

After upgrading from .NET 9 → .NET 10 (MAUI 10), layout rendering becomes broken on first navigation when using:

await Shell.Current.GoToAsync("//signin");

The page is shifted/collapsed/incorrectly arranged until the soft keyboard appears and disappears.
As soon as I tap an Entry → keyboard opens → hide keyboard → layout becomes correct.

This means the initial layout pass is wrong, and only a soft-input size change triggers correct measure/arrange.

This did NOT happen in .NET 9 on the same codebase.

Affected platforms

Android (primary issue)

iOS (same behavior)

Appears only in MAUI 10.

Reproduction Steps

1. Create a ContentPage with any layout (Grid / VerticalStackLayout).
2. Navigate to it using: await Shell.Current.GoToAsync("//signin");
3. Observe that the page loads with broken / shifted layout.
4. Tap Entry → keyboard shows → hide keyboard.
5. Layout suddenly becomes correct.

Expected Behavior

Page should render correctly on first appearance, without requiring a keyboard event to correct the layout.

Actual Behavior

First layout is incorrect.

Only after soft keyboard open/close does MAUI recalc layout properly.

InvalidateMeasure, ForceLayout, IView.InvalidateMeasure, Loaded event, delayed dispatch, etc. do NOT fix the issue.

This strongly suggests a regression in the new Layout system and/or Shell navigation lifecycle.

Notes

Issue appears when navigating with Shell absolute route (//route).

Same code works perfectly in .NET 9.

Attempts to fix using: IgnoreSafeArea , UseSafeArea, SafeAreaEdges, Dispatcher.DispatchDelayed, InvalidateMeasure → no effect.

Keyboard resize event is the only thing that fixes the page.

Sample XAML (minimal reproduction)
`

<VerticalStackLayout Spacing="16" Padding="20">

    <Image
        Source="dotnet_bot.png"
        HeightRequest="150"
        Aspect="AspectFit" />

    <Entry Placeholder="Email" />
    <Entry Placeholder="Password" />
    <Button Text="Sign in" />

</VerticalStackLayout>

This issue happens only when Shell.NavBarIsVisible="False" is set on the page.
With the NavBar visible → no problem.

Tested on .NET 10, Android emulator Pixel 5 API 33 — layout breaks on first load, then fixes itself after keyboard open/close.
