Steps to reproduce

1. Create a Blazor WASM project
2. Add a class in some nested namespace:

namespace GameStore.Client.Models;

public class Game
{
    public int Id { get; set; }

    public required string Name { get; set; }
}

4. Create a razor file with a code section that tries to use the clase above:

@code {
  [Parameter]
  public Game? Game { get; set; }
}

6. Click on the red squiggles under the type name and open the contextual Quick Fix:

Expected behavior

There should be an option to import the Models namespace, as there was one before:

Actual behavior

There's no option to import the Models namespace in this case.
