Thank you for the fix!

Would you run npm run changeset, select @shopify/hydrogen-react, and select patch change.

Would you add this test as well in useMoney.test.tsx. Watch out for the invisible character. If it doesn't copy well, inside the packages/hydrogen-react

1. run npm test:watch
2. replace expect(result.current).toEqual(... with expect(result.current).toMatchInlineSnapshot();
3. save to get a copy of the invisible space character

import {describe, expect, it} from 'vitest';
import {renderHook} from '@testing-library/react';
import {ShopifyProvider, ShopifyProviderProps} from './ShopifyProvider.js';
import {useMoney} from './useMoney.js';
