[iOS] Using safe area causes white area at the top upon entry focus.

Description

Problem: A white area appears at the top when an entry is tapped on and the soft keyboard opens up on iOS. Upon closing the keyboard, the area disappears. The area sometimes becomes bigger and permanent upon returning from a detail page.

Sample Code:


<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiApp2.MainPage"
            xmlns:ios="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.iOSSpecific;assembly=Microsoft.Maui.Controls"
             ios:Page.UseSafeArea="False"
             Shell.NavBarIsVisible="False">

    <Grid BackgroundColor="Yellow"
          IgnoreSafeArea="True">
        <Entry Text="Entry"
               BackgroundColor="White"
               VerticalOptions="Start"
               Margin="50" />
    </Grid>

</ContentPage>

Shell or Navigation page didn't make any difference

Steps to Reproduce

STEPS:

Create a new MAUI project .net 8.0.x
Set the content page's ios:Page.UseSafeArea="False" via XAML
Set the page's Shell.NavBarIsVisible="False" since we don't want to show the navbar
In the top-level child grid, set the IgnoreSafeArea to True so that it can be rendered on top of the iOS dynamic island or other controls
Add an Entry to the top-level child grid close to the dynamic island. The issue is not reproduced if the entry is not close to the physical phone non-safe areas.
Tap on the entry to enter something, the keyboard should open.

Observed Behavior: When the Keyboard opens, it seems like the entire layout drops down a bit as well. A white border appears at the very top of the display. Upon closing the keyboard, the area disappears.

Expected Behavior: The page top area should remain the same upon keyboard opening.

In addition to that, when coming back from another page the top white area becomes bigger and remains that way.
