Describe the bug

Razor Compiler created generic class constrains in wrong order
internal static class TypeInference
{
public static void CreateEBQuickGrid_0(global::Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder __builder, int seq, int __seq0, global::System.Object __arg0, int __seq1, global::System.Object __arg1, int __seq2, global::System.Linq.IQueryable __arg2, int __seq3, global::System.Func<TGridItem, global::System.Object> __arg3, int __seq4, global::Microsoft.AspNetCore.Components.EventCallback __arg4, int __seq5, TGridItem __arg5, int __seq6, global::Microsoft.AspNetCore.Components.RenderFragment __arg6, int __seq7, System.Action<global::EBBetreuungWeb.Client.Components.EBQuickGrid> __arg7)
where TGridItem : global::EBBetreuungWeb.Models.Data.IGetKey, class

Expected Behavior

where TGridItem : global::class,EBBetreuungWeb.Models.Data.IGetKey should work

Steps To Reproduce

1. Base razor component
   '''

[CascadingTypeParameter(nameof(TGridItem))]
public partial class QuickGrid<TGridItem> : IAsyncDisposable
{
.......
}

2. inheritance a new generic class from it and add 2 constrains (class and Interface)
   2.a) cs

[CascadingTypeParameter(nameof(TGridItem))]
public partial class EBQuickGrid<TGridItem> : QuickGrid<TGridItem> where  TGridItem: class , IGetKey 
{
...
}

2.b razor

@using Microsoft.AspNetCore.Components.QuickGrid
@using Microsoft.AspNetCore.Components.Rendering

@typeparam TGridItem
@inherits QuickGrid<TGridItem>

razor compiler generate

  internal static class TypeInference
    {
        public static void CreateEBQuickGrid_0<TGridItem>(global::Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder __builder, int seq, int __seq0, global::System.Object __arg0, int __seq1, global::System.Object __arg1, int __seq2, global::System.Linq.IQueryable<TGridItem> __arg2, int __seq3, global::System.Func<TGridItem, global::System.Object> __arg3, int __seq4, global::Microsoft.AspNetCore.Components.EventCallback __arg4, int __seq5, TGridItem __arg5, int __seq6, global::Microsoft.AspNetCore.Components.RenderFragment __arg6, int __seq7, System.Action<global::EBBetreuungWeb.Client.Components.EBQuickGrid<TGridItem>> __arg7)
            where TGridItem : global::EBBetreuungWeb.Models.Data.IGetKey, class
        {
