DAG tags filter not showing all tags in UI

What happened?

When dealing with a big number of tags, the DAG tags filter appears to be "truncating" the tags list.
Even when searching for a specific tag, it doesn't appear in the filter dropdown.

The example used to test this is showcased in details below. The idea is simple, to create a DAG with a significant amount of tags. The results can be seen in the images below.

What you think should happen instead?

All tags defined in the DAG should appear in the filter.

How to reproduce

Create a DAG with the following tags parameter setting:

...
with DAG(
    dag_id="basic_example",
    schedule="0 15 * * *",
    start_date=datetime(2024, 11, 6),
    catchup=False,
    tags=[str(i) for i in range(1000)]
) as dag:
...

Then go to the DAG tags filter and search for a tag greater than 150.

Hmm, was able to repro, checking it out. Looks like it limits responses to 50 tags
