Consumer not disconnecting properly

**Environment Information**
- OS [e.g. Mac, Arch, Windows 10]: Windows
- Node Version [e.g. 8.2.1]: 16.15.1
- NPM Version [e.g. 5.4.2]: 8.11.10
- C++ Toolchain [e.g. Visual Studio, llvm, g++]: VS code
- node-rdkafka version [e.g. 2.3.3]: 2.16.0

**Steps to Reproduce**
If I run the consumer.consume() function and then try to disconnect with the consumer.disconnect() function, it does not disconnect and stop the program. Interestingly, when repeating the same exact process but for the producer, it stops it correctly.

**node-rdkafka Configuration Settings**
'rebalance_cb': function(err : LibrdKafkaError, assignment : Assignment) {
if (err.code === CODES.ERRORS.ERR__ASSIGN_PARTITIONS) {
} else if (err.code == CODES.ERRORS.ERR__REVOKE_PARTITIONS){
} else {
// We had a real error
console.error(err);
}
