When having a promotion with products/skus associated through a collection, the productContext isn't prepared to create the items array inside benefits associated with the products of the collection

• Create a promotion
• Associate the products for this promotion through a collection
• Open one of the products that should have a promotion
• Open your browser's console
• Check on your React Dev Tools extension for productContextProvider
• Open benefits.items, it will be empty or with the sku with the same id of the collection

The only possible way to have benefits.items filled is filling all skus associated with the promotion instead of a cluster/collection
