The issue still persists when more than 2 empty mapped tasks are chained
with 2.4.3. Example code:
```
from datetime import datetime
from airflow import DAG
from airflow.decorators import task
with DAG(dag_id="break_mapping", start_date=datetime(2022, 3, 4)) as dag:
@task
def add_one(x: int):
return x + 1
@task
def say_hi():
print("Hi")
@task
def say_bye():
print("Bye")
added_values = add_one.expand(x=[])
added_more_values = add_one.expand(x=[])
added_more_more_values = add_one.expand(x=[])
say_hi() >> say_bye() >> added_values
added_values >> added_more_values >> added_more_more_values
```
