Before Creating the Bug Report

• I found a bug, not just asking a question, which should be created in GitHub Discussions.

• I have searched the GitHub Issues and GitHub Discussions of this repository and believe that this is not a duplicate.

• I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.

Runtime platform environment

It has noting to do with OS

RocketMQ version

I found this bug in 4.3.2 version, but the latest version also has this bug.

JDK Version

It has noting to do with JDK

Describe the Bug

Based on two principles:

1. For a message, its properties map and propertiesString should keep equal with each other, bug only propertiesString need to persist.
2. No matter which type of a message, such as transaction message、delay message、reconsumed message, when delivered into the final business topic, it shoud be pure, without and special marks, suan as TRANS_MSG、DELAY. Because thease marks are only RocketMQ inner, I think. A message with these marks is the
   source of many bugs, for instance, the half message with delay level bug.

This bug exists in two situations:

1. Transation message, before sendFinalMessage method, threee properties should be cleared before setPropertiesString, othewise, the final message will be delivered with the token of TRANS_MSG. and we have to save three more properties into commitlog.
2. Delay message, on messsage time up, have the save question.

Steps to Reproduce

Send a transaction message, a consumer receive it with TRANS_MSG property.

When reconsume a message, a consumer receive it with DELAY property.

What Did You Expect to See?

A final business message should be pure, without any rocketmq inner properties. It's really a source of bugs. Besides, it doesn't match the designment.
