Grid page visibility in the latest 2.3.1 release

Apache Airflow version

2.3.1 (latest released)

What happened

Hello team!

I have faced the problem with Grid visibility in the latest 2.3.1 release.

My issue (example)

1. Here is the end of dag code:

...
<code>
...
telegram_alert = TelegramOperator(
    task_id='telegram_alert'
    ,telegram_conn_id='telegram_bot_id'
    ,chat_id='telegram_chat_id'
    ,text="blablabla"
    ,dag=dag
)
python_task_1 >> python_task_2 >> puller >> telegram_alert

Grid:

1. Delete task with telegram alert: Code in the end of dag code:

...
<code>
...
python_task_1 >> python_task_2 >> puller

Grid after deleting (Telegram alert task disappeared):

Grid after triggering dag again:

1. Return task with telegram alert in the dag as it was at the begining. Grid:

PS:

As I remember in 2.3.0 there wasn’t such bug. I tried to roll back airflow image (from 2.3.1 to 2.3.0) and restart containers but faced error during starting webserver: alembic.util.exc.CommandError: Can’t locate revision identified by ‘1de7bc13c950’

I see the same error when try to execute such command: airflow db downgrade --to-version 2.3.0 Please help to me to roll back the airflow version or may be I can get some patch which fix this bug.

What you think should happen instead

The Grid must be visible at any time at any case

How to reproduce

Steps to reproduce:

1. Create dag with N tasks
2. Trigger dag
3. Delete 1 task from dag
4. Trigger dag
5. Return deleted task to dag
6. Try to see DagRun history on the Grid page.

Many dags became unvisible on the Grid page and it is critical for us

I’ve just upgraded to 2.3.2rc2 and everything is ok.

We were running 2.3.2rc1 on production since last monday and we had non problem at all.
