这个浅拷贝示例会输出什么？
csharp
using System;
using System.Collections.Generic;
Bundle original = new(["draft"]);
Bundle copy = original with { };
copy.Labels.Add("reviewed");
Console.WriteLine(original.Labels.Count);
Console.WriteLine(ReferenceEquals(original.Labels, copy.Labels));
public sealed record Bundle(List<string> Labels);
