URL: https://github.com/apache/airflow/issues/65159
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.1.8
### What happened and how to reproduce it?
When there is a dag run with many tasks (over 26 approximately), you need to
scroll to see some of the tasks in the grid view. The scrolling does not work
for the Gantt chart view. The grid still scrolls but the Gantt chart does not
actually scroll down. The tasks in the Gantt view get mismatched with the tasks
in the grid view when you scroll down, and you cannot see the Gantt view for
the bottom tasks.
This can be reproduced by creating and running a dag with over 26 tasks.
Here is an example:
```
from airflow.sdk import dag, task
from pendulum import datetime
@dag(
dag_id="test_gantt",
start_date=datetime(2024, 1, 1),
schedule=None,
catchup=False,
)
def test_gantt():
@task
def make_task(n: int) -> None:
print(f"Task {n}")
tasks = [make_task.override(task_id=f"task_{i}")(i) for i in range(1,
31)]
for i in range(len(tasks) - 1):
tasks[i] >> tasks[i + 1]
test_gantt()
```
Once this dag runs, select the options drop down and check "Show Gantt".
Then, select the dag run and scroll down to see the tasks at the bottom. You
will observe that the grid view scrolls down but the Gantt chart does not.
### What you think should happen instead?
The Gantt chart should be able to scroll down.
