Back Button On Modals

Modals need a native button when they are opened from another modal. Modals only have a closeout (X) button, which is insufficient because users expect to see the previous modal when the last modal is closed. For instance, when a user opens a modal that contains a linked list, then opens one of the linked-list items in another modal, they can’t go back to the previous modal with the linked list.
