ver.4.5.6 HttpServerRequest.isExpectMultipart wrong results returned.

[bigtrouble]

Version

4.5.6

Context

public static void main(String[] args) {
    val vertx = Vertx.vertx();
    val server = vertx.createHttpServer(new HttpServerOptions());
    val router = Router.router(vertx);
    server.requestHandler(router);
    router.route()
      .handler(BodyHandler.create())
      .handler(ct -> {
        val req = ct.request();
        System.out.println("contentType:" + req.getHeader("content-type"));
        System.out.println("isExpectMultipart:" + req.isExpectMultipart());
        ct.response().end("ok");
      });

    server.listen(8080)
      .compose(t -> WebClient.create(vertx)
        .postAbs("http://127.0.0.1:8080")
        .sendMultipartForm(MultipartForm.create().attribute("a1", "11"))
        .mapEmpty()
      )
      .onComplete(ar -> {
        server.close();
        vertx.close();
      });
  }

The console returned the following results:

contentType:multipart/form-data; boundary=3dfbb691c889090f
isExpectMultipart:false

But in v4.5.5 the same test code isExpectMultipart returns true.
