Clipboard does copy/paste objects when complied with .Net8

Describe the bug

Clipboard does copy/paste objects when complied with .Net8

Steps to Reproduce

Create a new Avalonia project. Set the targets to: net7.0 Create a model that includes the [Serializable] attribute. For example:

    [Serializable]
    public class MyTestModel
    {
        public int Id { get; set; }
        public string? Name { get; set; }

        public MyTestModel() 
        { 
        }
    }

Update the MainView to create the model and copy then paste the model to and from the clipboard like so:

public partial class MainView : UserControl
{
    public MainView()
    {
        InitializeComponent();
        Loaded += MainView_Loaded;
    }

    private void MainView_Loaded(object? sender, Avalonia.Interactivity.RoutedEventArgs e)
    {
        TestAsync().GetAwaiter().GetResult();
    }

    private async Task TestAsync()
    {
        var m = new MyTestModel()
        {
            Id = 1,
            Name = "Test",
        };

        var dataObject = new DataObject();
        dataObject.Set("my-app-person", m);

        var clipboard = TopLevel.GetTopLevel(this)!.Clipboard!;
        await clipboard.SetDataObjectAsync(dataObject);

        var r = await clipboard.GetDataAsync("my-app-person");
        Debug.WriteLine(r);
    }
}

Run the program. Notice the variable "r" is returned as expected. Modify both Avalonia projects to target to net8.0 Run the program. Notice the variable "r" is null.

Oops wrong project. Please delete me.

Don't do GetAwaiter.GetResult. that's evil imo

@timunie I know thanks. It's a test app to show off the bug with the least lines of code.
