### 💻 Code

```ts
export interface Properties {
propertyA: number;
propertyB: string;
}

export function getPropertyValue_Ok(
properties: Properties,
propertyName: keyof Properties,
): Properties[typeof propertyName] {
return properties[propertyName];
}

export class A {
public getPropertyValue_Ok(
properties: Properties,
propertyName: keyof Properties,
): Properties[typeof propertyName] {
return properties[propertyName];
}

// error TS4055: Return type of public method from exported class has or is using private name 'propertyName'.
protected getPropertyValue_Error(
properties: Properties,
propertyName: keyof Properties,
): Properties[typeof propertyName] {
return properties[propertyName];
}

// error TS4073: Parameter 'propertyValue' of public method from exported class has or is using private name 'propertyName'.
protected setPropertyValue_Error(
properties: Properties,
propertyName: keyof Properties,
propertyValue: Properties[typeof propertyName],
) {
// TODO
}
}
```

### 🙁 Actual behavior

The protected methods fail to generate declaration with TS4055 or TS4073.

### 🙂 Expected behavior

The protected methods should be able to generate declaration similar to the public method or function.

### Additional information about the issue

I wonder if there's a way to temporarily suppress this error, becuase ts-ignore doesn't seem to work when generating declaration.

从链接的 TypeScript Playground 和提供的声明生成复现开始，重点关注 class A 中的受保护方法以及 TS4055/TS4073 诊断。将它们的行为与公共方法和独立函数进行比较；完成的标准是受保护方法的声明生成能够在没有这些错误的情况下成功完成。
