Pre-order - Support pre-order in Quick Order List section

The pre-order widget/messaging does not appear in the theme's native "Quick order list" section on the product page. When a product is set to "Continue selling when out of stock," it can be ordered from the quick order list but without any pre-order messaging. Context: The Quick order list is a native Shopify theme section that sits on the product page but is separate from the Product information section where buy buttons and our widget normally render.
