Currently the delivery of a kit is not allowed if the product has a configured modal.

Simulation

1-Configure a carrier to accept only deliveries of a specific modal.

2-Configure this modal in a kit SKU and also in its component SKUs.

3-Try to make a purchase of this kit to be delivered by the carrier that has the modal.

Workaround

Configure the shipping policy so that it also delivers undefined modals.

Obs: This workaround is only available if ALL components inside the KIT has the modal configured,
