[BUG] useLayoutEffect warning in dev mode

[joulev]

Describe the bug
When using react-tooltip, there is a useLayoutEffect warning, although the tooltip itself works fine.

Warning: useLayoutEffect does nothing on the server, because its effect cannot be 
encoded into the server renderer's output format. This will lead to a mismatch 
between the initial, non-hydrated UI and the intended UI. To avoid this, 
useLayoutEffect should only be used in components that render exclusively on the 
client. See https://reactjs.org/link/uselayouteffect-ssr for common fixes.

Additional context
The repro repo uses Next.js 13, but this one is different from #933 as I have disabled SWC minification.

According to this link a few big react projects currently use the following workaround:

import { useLayoutEffect, useEffect } from 'react';
const useIsomorphicLayoutEffect =
  typeof window !== 'undefined' ? useLayoutEffect : useEffect;
export default useIsomorphicLayoutEffect;

Apparently there aren't any undesired side effects, so we're probably going to include this soon.

Thanks for reporting it.

I'm seeing this on "react-tooltip": "^5.21.6",

@k2xl please open a new issue and provide more information about your environment (framework you're using and the version, etc). If possible, a reproducible sample would help a lot.
