I would use a stable deps like useOnMount does:
const EMPTY = [] as unknown[];
// ...
useEnhancedEffect(effect, EMPTY);

It's not the first time I see useEnhancedEffect cause such issue, the hook makes it less apparent that useLayoutEffect is used, and that it runs on a different cycle than useEffect.

As far as I know, using
useOnMount()is wrong in this context. We need to clear the timeout synchronously with the component unmounts.See facebook/react#19671, with https://codesandbox.io/p/sandbox/unruffled-banzai-7zzr6k?file=%2Fsrc%2FDemo.tsx that illustrates the difference in behavior:
It seems the root cause of why mui/mui-x#14987. This fix is upstream of: mui/mui-x#16031, but it might be best to first merge downstream, so we test it with a smaller userbase.
