### Apache Airflow version
3.0.1
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
I recently updated my Airflow version (in Docker) from 2.10.2 to 3.0.1. I'm
currently experiencing an issue with the triggering of a DAG from another DAG.
When the second DAG is triggered its first task is marked as "queued" and the
state does not change therefore making the application stuck.
### What you think should happen instead?
_No response_
### How to reproduce
The situation is the following:
1. DAG1 triggers some Python logic and inside this logic it triggers with
Airflow REST API the execution of DAG2. Then it checks the state of the DAG2
every minute to see if the execution was successful. In that case it will exit.
2. DAG2 will run two tasks and then the third task will trigger DAG3 by
means of `TriggerDagRunOperator` imported from
`airflow.providers.standard.operators.trigger_dagrun`:
```
trigger_run_no_consent_cleanup = TriggerDagRunOperator(
task_id="execute_run_no_consent_cleanup",
trigger_dag_id="run_no_consent_cleanup",
wait_for_completion=True,
conf={"run_uuid": "{{ dag_run.conf['run_uuid'] }}"},
poke_interval=1
)```
In addition in the background there is DAG4 that is triggered autonomously
every minute. The problem is that when DAG1 is triggered, once DAG3 is launched
the process is stuck. It was working fine before on the older version of
Airflow.
DAG3 has 2 tasks to execute and the first task is not even triggered. It
just hangs in "queued" state and I have cannot extract any logs from it to
understand why it is waiting. DAG1,2,3 all specified the parameter
`max_active_runs=1` but that should be specific to the DAG and should not
influence the tasks of another DAG.
Dag definition example:
```
@dag(schedule=config.no_consent_cleanup_schedule,
start_date=config.airflow_start_date,
max_active_runs=1,
catchup=False,
description="Triggered DAG to cleanup",
render_template_as_native_obj=True
)
```
Any idea about what causes this conflict state? Thank you.
