DataObject contains wrong data for file drop under .Net 9 RC1

[IrinaPykhova]

.NET version

.Net 9 RC1

Did it work in .NET Framework?

Yes

Did it work in any of the earlier releases of .NET Core or .NET 5+?

it worked correctly in .Net 8, here is what I expect to see:

Issue description

at file drop action DataObject.GetDataPresent method returns wrong value, so, we can't rely on it any more. Here is what I see in debugger:

You see, it shows single data format Shell IdList Array, but at the same time GetDataPresent return true for any existent or not existent formats I ask

Steps to reproduce

Create Windows Forms application, set Form AllowDrop property to true and add handler for Form.DragOver event, something like this:

private void Form1_DragOver(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(typeof(C1.Schedule.Appointment)))
    {
        C1.Schedule.Appointment app;
        app = (C1.Schedule.Appointment)e.Data.GetData(typeof(C1.Schedule.Appointment));
        app.Subject = "my test dragged appointment";
    }
}

You can check for any types which are present in your application instead of Appointment type in this snippet.
Run application, select any file in FileExplorer and drag it over the form. You can set breakpoint in debugger and play with VS Watch window to explore DataObject content. Under .Net 9 you can't see any more that it was a file and you get all wrong information about presented Data.
