Command Palette

Steps to reproduce

Let's have a simple page full of squirrels. Scrolling in this page cause Command Palette fail fast.

class ChaosPage : DynamicListPage
{

    private ListItem[] _test;

 
    public ChaosPage()
    {

        _test = Enumerable.Range(1, 40).Select(t => new ListItem(new NoOpCommand()) { Title = "Item " + t }).ToArray();

        Task.Run(Chaos);
        Task.Run(Chaos);
        Task.Run(Chaos);
    }



    private async Task? Chaos()
    {
        while (true)
        {
            foreach (var listItem in this._test)
            {
                try
                {
                    var f = Directory.GetFiles("X:\\Squirrels");
                    var randomFile = f[new Random().Next(f.Length)];
                    listItem.Icon = IconInfo.FromStream(await ThumbnailHelper.GetThumbnail(randomFile!));
                }
                catch (Exception ex)
                {
                    Logger.LogError(ex);
                }
            }
        }
    }


    public override IListItem[] GetItems()
    {
        return this._test;
    }
}
