When pre_routing_handler or pre_request_handler answers a WebSocket upgrade request, Server::process_request returns before the drain of an unread body and closes the connection only for a 4xx/5xx. A 2xx/3xx answer to an upgrade request with a framed body left that body to be parsed as the next request on the keep-alive connection. Those two early returns now close the connection when the request has a framed body, as the Expect rejection already does.
