It is possible for WebPaymentCoordinatorProxy to send IPC messages to the WP when the connection is null. This can happen when a WP terminates while a payment sheet is showing, and since the proxy will be alive, it will end up sending a DidCancelPaymentSession message in its destructor. Unfortunately, this causes the UI process to terminate, which is a bad user experience for, say, Safari users. We should make sure WebPaymentCoordinatorProxy is smart enough to not send this IPC message if the WP is not alive.
