### 💻 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.

Start with the linked TypeScript Playground and the provided declaration-generation reproduction, focusing on the protected methods in class A and the TS4055/TS4073 diagnostics. Compare their behavior with the public method and standalone function; done means declaration generation succeeds for the protected methods without those errors.
