window.ipcRenderer.off is not working on renderer process.

[sven0227]

function App() { const [count, setCount] = useState(0);

const handler = useCallback(() => { console.log("added received!!!"); }, []);

useEffect(() => { window.ipcRenderer.on("added", handler); return () => { window.ipcRenderer.off("added", handler); }; }, []); ... }

// main.ts ipcMain.handle("add", (event) => { console.log("add"); event.sender.send("added", { message: "added" }); });

The "added" handler on renderer process is double called every main process sends "added" event. It means that window.ipcRenderer.off is not working on renderer process.
