useLocalStorageHook set defaultValue to undefined but get empty string

What package has an issue

@mantine/hooks

Describe the bug

Hello, why choose Nullish coalescing operator to make defaultValue which is undefined or null to empty string in useLocalStorageHook?

It’s a little weird if I expect an undefined/null defaultValue but get an empty string.

Also, is there a typo here in use-local-storage?

If set to true, value will be update is useEffect after mount

Possible fix

const readStorageValue = useCallback(
      (skipStorage?: boolean): T => {
        if (typeof window === 'undefined' || !(type in window) || skipStorage) {
          return defaultValue as T;
          // return (defaultValue ?? '') as T;
        }

        const storageValue = window[type].getItem(key);

        return storageValue !== null ? deserialize(storageValue) : (defaultValue as T);
        // return storageValue !== null ? deserialize(storageValue) : ((defaultValue ?? '') as T);
      },
      [key, defaultValue]
    );
