Typescript interfaces that "extend" another interface and overload a function on the base interface causes a tsc error

[dunhor]

E.g. the definition of IWebSocket gets generated as:

    interface IWebSocket extends Windows.Foundation.IClosable {
        readonly outputStream: Windows.Storage.Streams.IOutputStream;
        connectAsync(uri: Windows.Foundation.Uri): Windows.Foundation.WinRTPromise<void, void>;
        setRequestHeader(headerName: string, headerValue: string): void;
        close(code: number, reason: string): void;
        addEventListener(type: "closed", listener: Windows.Foundation.TypedEventHandler<Windows.Networking.Sockets.IWebSocket, Windows.Networking.Sockets.WebSocketClosedEventArgs>): void;
        removeEventListener(type: "closed", listener: Windows.Foundation.TypedEventHandler<Windows.Networking.Sockets.IWebSocket, Windows.Networking.Sockets.WebSocketClosedEventArgs>): void;
    }

Which produces the following error because IClosable declares the function close(): void

windows/WinRTTurboModule/Generated Files/types/Windows.Networking.Sockets.d.ts:65:15 - error TS2430: Interface 'IWebSocket' incorrectly extends interface 'IClosable'.
  Types of property 'close' are incompatible.
    Type '(code: number, reason: string) => void' is not assignable to type '() => void'.
