I'd like to add that the same behavior is observed while using the WebClientSession, due to the same bug.

var webClient = WebClient.create(vertx);
var webClientSession = WebClientSession.create(webClient)
    .addHeader("Authorization", "Bearer: 4gse4kgsel")

// No 'Authorization' header is being sent to server, just the 'User-Agent'
var request = webClientSession
    .getAbs("http://example.com/api/v1/someEndpoint")
    .send()
