 If you use Next.js's support for client side SPA-style navigation by using `next/navigation`, then when customers navigate from page to page only the route component will be re-rendered. This means that if you have a Redux store created and provided in the layout component it will be preserved across route changes. This is not a problem if you are only using the store for global, mutable data. However, if you are using the store for per-route data then you will need to reset the route-specific data in the store when the route changes.

In order to ensure that we have the correct name in the store we need to set the value in the store any time the `ProductName` component is initially rendered, which happens on any route change to the product detail route.
