Test steps

1. Navigate to admin area.
2. Create simple product with qty = 1
3. Navigate to storefront.
4. Register and login with customer.
5. Add product to cart and proceed to checkout.
6. Place order.
7. Navigate to customer account dashboard.
8. Navigate to "My Orders" tab.
9. Test expects "Reorder" button hides from page.

Additional Info

Standard magento behaviour - "Reorder" button hides immediately after place order, but. On MSI "Reorder" button hides only after shipment created #680.
Additional steps with shipment placement should be added into test before assertions.
