TypeScript 显示方法参数名称的特性(Feature)不能正确处理方法重载(因此变量名来自错误的重载，可能是来自第一个方法定义),

类型：Bug
当代码如下所示时：

public async cancelBooking(
    internalBookingId: number,
    company: Companies,
    dataStoreService: DataStoreService,
    bookingsService: BookingsService,
  ): Promise<void>;
  public async cancelBooking(
    booking: ExtendedBookingSystemBooking,
    company: Companies,
    dataStoreService: DataStoreService,
    bookingsService: BookingsService,
  ): Promise<void>;
  public async cancelBooking(
    booking: number | ExtendedBookingSystemBooking,
    company: Companies,
    dataStoreService: DataStoreService,
    bookingsService: BookingsService,
  ) {
    ...
  }

然后从代码的其他部分调用此方法，并使用ExtendedBookingSystemBooking作为第一个参数，内联方法参数提示显示“internalBookingId”作为方法参数名称，尽管VSCode知道第二个方法定义被使用(在方法调用上悬停时会正确显示)。

我无法复现这个问题。你能提供一个本地的代码示例，让我们看看如何演示这个问题吗？

我尝试过：

declare function foo(str: string): void;
declare function foo(num: number): void;

foo("string");

foo(12345);

你好，@RyanCavanaugh - 对于简单的情况，它可能运行良好。请尝试使用这个"最小化"复现器：

class ZZZ {
  id: number;
}

class CCC {
  activities: number[];
}

class XYZ {
  public async cancelBooking(
    internalBookingId: number,
    company: ZZZ,
  ): Promise<void>;
  public async cancelBooking(booking: CCC, company: ZZZ): Promise<void>;
  public async cancelBooking(booking: number | CCC, company: ZZZ) {}

  public async XYZ() {
    return this.cancelBooking(
      { activities: [1, 2, 3] },
      {
        id: 1,
      },
    );
  }
}

type HasID = {
  id: number;
}

type Numbers = {
  n: number[];
}

declare function func(bad1: number, bad2: HasID): void;
declare function func(ok_1: Numbers, ok_2: HasID): void;

// Inlay hint shows bad1/bad2, should show ok_1/ok_2
func(
  { n: [1, 2, 3] },
  {
    id: 1,
  },
);
