When using custom HTTP client, HttpClient's urlBuild does not work

[springeye]

Ktorfit version

1.11.0

What happened and how can we reproduce this issue?

Set the baseURL of ktorfit to empty, and use urlbuild to dynamically return the baseURL when building an HTTP client

val client=HttpClient {
            defaultRequest {

                if(headers["Content-Type"].isNullOrEmpty()){
                    header("Content-Type","application/json")
                }
                url{
                    val prefer: AppPreferences =get()
                    val url=runBlocking { prefer.host() }
                    //this url should https://api.github.com
                    url
                }
            }
            install(Logging) {
                logger = object: Logger {
                    override fun log(message: String) {
                        Napier.v("HTTP Client", null, message)
                    }
                }
                level = LogLevel.BODY
            }
            install(HttpCookies)
            install(ContentNegotiation) {
                json(json= get())
            }
        }.also { Napier.base(DebugAntilog()) }

    val kf=ktorfit {
            baseUrl("",false)
            httpClient(client)
            converterFactories(
                CallConverterFactory()
            )
        }

What did you expect to happen?

When I access api/v1/auth/signin, I should access https://api.github.com/api/v1/auth/signin ,

And the actual situation is http://localhost/api/v1/auth/signin

Is there anything else we need to know about?
