I suspect the fix is to simply use React.useEffect. I'm a little surprised the CI build and tests passed. That may be a separate issue to investigate.

Somewhat related, I think that useEffect might be slightly incorrect since the key isn't in the dependency array too. Perhaps it should be modeled after the one here: https://usehooks.com/useLocalStorage/
