Shipping Discount Functions Can't See Bundled Products in the Cart

Has anybody else noticed that if a bundle (from the Shopify Bundles app) is in the cart, it is missing from Shopify Functions input?

For example, if the only item in the cart is a bundle, cart.deliveryGroups.cartLines is an empty array.

If there are 3 products in the cart, and one is a bundle, cart.deliveryGroups.cartLines will contain only the 2 non-bundle products.

8 separate merchants have reported this issue to us.

My team reached out to Shopify Partners support in September, and they told us, “it seems like the issue highlighted is a known issue that our developers are aware of and working to fix.” Is there an existing thread about this that I can subscribe to?

Thanks in advance.
