- `ProductListContextProvider` provides `setIsLoading` function as well as `isLoading`.
- `Discover` uses these values from context, instead of keeping a loading state in itself.
- `FeedbackModal` calls `maybSetTimeout` when `isLoading` changes. If `isLoading` isn't truthy, and snackbar hasn't already rendered, it sets a timeout of 5 seconds to show it.
- Removed wrapping <WooFooterItem> from around Footer component, so it's no longer a child of the WooCommerce Admin `.woocommerce-layout__footer` footer.
- Removed the `position: relative` from `.woocommerce-layout__footer`. It needs to be `position: fixed`.
- Added FooterContent component to Footer, to allow the layout we want.
- Changed use of context. This now only has states for the selected tab and loading state.
- We use this context in `Tabs` and `Content` to keep track of which tab is selected, and set the selected tab.
- We also use it in `Discover` and `Extensions`, which both report loading state to the context. This allows us to use it to only render the snackbar when loading is complete.
- Extensions: moved `productList` and `setProductList` and logic for getting product list from the context provider to a state in this component. We don't need to share the list of products in the context.
- Renamed `ProductListContext`, `ProductListContextProvider` and `productListContextValue` to more generic `MarketplaceContext`, `MarketplaceContextProvider` and `marketplaceContextValue`.
- Renamed a constant and created constants for API paths.
- Only shows snackbar after content has loaded, and after a timeout. We set a date `marketplace_redesign_2023_last_shown_date` in local storage to ensure we only show one snackbar.
We were hitting the WCCOM API directly from the front end. However,
that limits of in terms of caching and reducing the load on WCCOM.
To prevent that, we added a REST API endpoint. This endpoint
fetches discover page content from WCCOM and puts in a transient.
This is actually how the page works in the previous version. So
we were able to reuse a lot of the code.
