Bug in .NET MAUI Custom ScrollView for iOS

I’m currently trying to create a custom ScrollViewer that has a zoom and pan functionality but whenever the screen’s zoomed and the app resumes from a sleep state, the view changes its position, shrinks its ScrollHeight , and zooming out positions the grid on the upper left of the screen. (Refer to the screenshot below.)

It could be a bug in .NET Maui itself but I’m not sure. (on Xamarin.Forms it works)

Is there a work-around or a way to resolve it?

View after zooming out:

Here’s the code below to reproduce the problem:

MainPage.xaml

<?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"
             xmlns:controls="clr-namespace:MauiAppTest"
             x:Class="MauiAppTest.MainPage">

    <controls:ZoomableScrollView>
        <Grid Background="pink">
            <VerticalStackLayout
            Padding="30,0"
            Spacing="25">
                <Image
                Source="dotnet_bot.png"
                HeightRequest="185"
                Aspect="AspectFit"
                SemanticProperties.Description="dot net bot in a race car number eight" />

                <Label
                Text="Hello, World!"
                Style="{StaticResource Headline}"
                SemanticProperties.HeadingLevel="Level1" />

                <Label
                Text="Welcome to &#10;.NET Multi-platform App UI"
                Style="{StaticResource SubHeadline}"
                SemanticProperties.HeadingLevel="Level2"
                SemanticProperties.Description="Welcome to dot net Multi platform App U I" />

                <Button
                x:Name="CounterBtn"
                Text="Click me" 
                SemanticProperties.Hint="Counts the number of times you click"
                Clicked="OnCounterClicked"
                HorizontalOptions="Fill" />
            </VerticalStackLayout>
        </Grid>
    </controls:ZoomableScrollView>
</ContentPage>

ZoomableScrollView.cs (Custom ScrollView)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MauiAppTest
{
    public class ZoomableScrollView : ScrollView
    {

    }
}

ZoomableScrollViewHandler.cs

using Microsoft.Maui.Handlers;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UIKit;

namespace MauiAppTest.Platforms.iOS
{
    public class ZoomableScrollViewHandler : ScrollViewHandler
    {
        protected override void ConnectHandler(UIScrollView platformView)
        {
            base.ConnectHandler(platformView);
            if(platformView != null)
            {
                platformView.MinimumZoomScale = 1;
                platformView.MaximumZoomScale = 3;
                platformView.ViewForZoomingInScrollView += (UIScrollView sv) =>
                {
                    return platformView.Subviews[0];
                };
            }
        }
        protected override void DisconnectHandler(UIScrollView platformView)
        {
            base.DisconnectHandler(platformView);
        }
    }
}

MauiProgram.cs

using Microsoft.Extensions.Logging;
#if IOS
using  MauiAppTest.Platforms.iOS;
#endif

namespace MauiAppTest
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });
#if IOS
builder.ConfigureMauiHandlers(handlers => 
handlers.AddHandler(typeof(ZoomableScrollView),typeof(ZoomableScrollViewHandler)));
#endif
#if DEBUG
            builder.Logging.AddDebug();
#endif

            return builder.Build();
        }
    }
}

I expected that the ScrollViewer would work without problem as it worked on Xamarin.Forms.

Things I’ve tried including:
・Using a ScrollViewRenderer(with the use of maui.compatibility)
・Tried getting the ZoomScale and ContentOffset during OnSleep, then setting them again during OnResume.
