Duplicate messages are published and throws TimeoutException

[sann3]

Environment details

1. google-cloud-pubsub
2. Linux version 5.15.153.1-microsoft-standard-WSL2
3. Java Corretto-21.0.3.9.1 (build 21.0.3+9-LTS)
4. version(s): com.google.cloud:google-cloud-pubsub:1.131.0

Steps to reproduce

1. Some times a message is published multiple times (upto 7 times), since it is not getting the acknowledge back. Finally getting timeout exception.
2. Not happening always, only happens to some random messages

Code example

    application.yaml
      max-buffered-messages: 1
      initial-retry-delay-in-millis: 100
      retry-delay-multiplier: 2.0
      max-retry-delay-in-seconds: 60
      initial-rpc-timeout-in-seconds: 1
      rpc-timeout-multiplier: 1.0
      max-rpc-timeout-in-seconds: 600
      total-timeout-in-seconds: 600

       RetrySettings defaultRetrySettings =
                RetrySettings.newBuilder()
                        .setInitialRetryDelay(
                                Duration.ofMillis(pubSubProperties.getInitialRetryDelayInMillis()))
                        .setRetryDelayMultiplier(pubSubProperties.getRetryDelayMultiplier())
                        .setMaxRetryDelay(
                                Duration.ofSeconds(pubSubProperties.getMaxRetryDelayInSeconds()))
                        .setInitialRpcTimeout(
                                Duration.ofSeconds(
                                        pubSubProperties.getInitialRpcTimeoutInSeconds()))
                        .setRpcTimeoutMultiplier(pubSubProperties.getRpcTimeoutMultiplier())
                        .setMaxRpcTimeout(
                                Duration.ofSeconds(pubSubProperties.getMaxRpcTimeoutInSeconds()))
                        .setTotalTimeout(
                                Duration.ofSeconds(pubSubProperties.getTotalTimeoutInSeconds()))
                        .build();
        Publisher publisher =
                builder.setEnableMessageOrdering(true)
                        .setRetrySettings(defaultRetrySettings)
                        .build();
        ApiFuture<String> future = publisher.publish(pubsubMessage);
        future.get(5000, TimeUnit.MILLISECONDS);
