// This class manages the interaction between the renderer (through the
// PaymentRequestClient and Mojo stub implementation) and the desktop Payment UI
// (through the PaymentRequestDelegate). The API user (merchant) specification
// (supported payment methods, required information, order details) is stored in
// PaymentRequestSpec, and the current user selection state (and related data)
// is stored in PaymentRequestState.
// As the PaymentRequest is a DocumentService, its lifetime is managed by the
// RenderFrameHost that the request is created for, and will be destroyed when
// the current document is or when the mojom::PaymentRequest connection is lost.
// The PaymentRequest is also a WebContentsObserver, which has historically
// been used to track the lifetime of the RenderFrameHost, which is now done by
// DocumentService. Instead, the WebContentsObserver is used to watch for
// navigations that would destroy this object's document _in the future_ in
// order to record metrics.
