EventCallback<T> Error cannot convert from 'method group' to 'EventCallback'

Describe the bug

Using the following two components, the compiler emits an error in the Parent component in the OnSelect event parameter.

Error cannot convert from ‘method group’ to ‘EventCallback’

<Child Data="@Data" OnSelect="@OnSelect">
</Child>

Is this an issue or I am doing this wrong ?

To Reproduce

@*Parent.razor*@

@page "/Parent"

<div>
    <Child Data="@Data" OnSelect="@OnSelect">
    </Child>
</div>

@functions {
    List<Item> Data = new List<Item>();

    private void OnSelect(Item item)
    {        
    }
}

@*Child.razor*@

@typeparam TData

<div>
    @foreach (var item in Data)
    {
        <button onclick="@(() => OnSelect.InvokeAsync(item))"></button>
    }
</div>

@functions {
    [Parameter]
    public IEnumerable<TData> Data { get; set; }

    [Parameter]
    private EventCallback<TData> OnSelect { get; set; }
}

// Item.cs
public class Item
{
     public Item()
     {

     }
}

Using async and Task does not change anything - the error remains.

The only way I am able to make it work is by doing the following in the Parent component event handler :

<Child Data="@Data" OnSelect2="@((Item item) => { OnSelect(item); })"></Child>

instead of :

<Child Data="@Data" OnSelect="@OnSelect">

Seems kind of strange to me that it would need to be done that way though.

Hey I have Installed Preview 7 but I still get this error, shouldn’t this be fixed?
