Why does memory usage continuously increase when using ListView in Maui?

Actual Behavior:

• Memory usage continuously increases over time
• Memory is not being released even with proper disposal patterns implemented

Code Implementation:`using System.Collections.ObjectModel;

namespace MauiListView{public class Message{public string? Content { get; set; }public DateTime Timestamp { get; set; }}

public partial class MainPage : ContentPage, IDisposable{    private const int MAX_MESSAGES = 10;    private readonly ObservableCollection<Message> messages;    private IDispatcherTimer? timer;    private bool isDisposed;    public MainPage()    {        InitializeComponent();        messages = new ObservableCollection<Message>();        MessageListView.ItemsSource = messages;    }    private void StartMessageGeneration()    {        // 이전타이머가있다면정리        StopAndDisposeTimer();        timer = Application.Current?.Dispatcher.CreateTimer();        if (timer != null)        {            timer.Interval = TimeSpan.FromSeconds(1);            timer.Tick += Timer_Tick;            timer.Start();        }    }    private void StopAndDisposeTimer()    {        if (timer != null)        {            timer.Stop();            timer.Tick -= Timer_Tick; // 이벤트핸들러해제            timer = null;        }    }    private void Timer_Tick(object? sender, EventArgs e)    {        if (messages == null) return;        var message = new Message        {            Content = $"새로운메시지 {DateTime.Now}",            Timestamp = DateTime.Now        };        MainThread.BeginInvokeOnMainThread(() =>        {            messages.Insert(0, message);            while (messages.Count > MAX_MESSAGES)            {                messages.RemoveAt(messages.Count - 1);            }        });    }    public void Dispose()    {        Dispose(true);        GC.SuppressFinalize(this);    }    protected virtual void Dispose(bool disposing)    {        if (!isDisposed)        {            if (disposing)            {                StopAndDisposeTimer();                messages.Clear();                MessageListView.ItemsSource = null;            }            isDisposed = true;        }    }    protected override void OnAppearing()    {        base.OnAppearing();        StartMessageGeneration();    }    protected override void OnDisappearing()    {        base.OnDisappearing();        StopAndDisposeTimer();    }    ~MainPage()    {        Dispose(false);    }}

}`

Environment:

• .NET MAUI version: 8.0
• Platform tested: Windows

What I've tried:

1. Implemented IDisposable pattern
2. Clearing ItemsSource on disposal
3. Properly unsubscribing from events
4. Limiting collection size with MAX_MESSAGES
5. Using MainThread.BeginInvokeOnMainThread for UI updates

Expected Behavior:

• ListView should maintain stable memory usage
• Memory should be properly cleaned up when items are removed from the ObservableCollection
