Hello. How do you test a WebSocket client? It doesn't seem like I can use

handleWebSocketConversation

or anything related to WebSocket inside `addHandler`:

val ktorClient = HttpClient(MockEngine) {
                engine {
                    addHandler { request ->
                        handleWebSocketConversation {}
                    }
                }
            }

If I'm understanding you correctly, it isn't currently supported: https://github.com/ktorio/ktor/issues/1413
