### Apache Airflow version

2.6.0

### What happened

Stream logging works as long as the task is running. Once the task finishes, no logs are printed to the UI (only the hostname of the worker is printed)

### How to reproduce

Start an airflow task. You should be able to see the logs coming in as a stream, once it finishes, the logs are gone
