Airflow 2.3.0: can't filter by owner if selected from dropdown

[ecodina]

Apache Airflow version

2.3.0 (latest released)

What happened

On a clean install of 2.3.0, whenever I try to filter by owner, if I select it from the dropdown (which correctly detects the owner's name) it returns the following error:

DAG "ecodina" seems to be missing from DagBag.
Webserver's log:

Instead, if I write the owner's name fully and avoid selecting it from the dropdown, it works as expected since it constructs the correct URL:

my.airflow.com/home?search=ecodina

What you think should happen instead

The DAGs table should only show the selected owner's DAGs.

How to reproduce

• Start the Airflow Webserver
• Connect to the Airflow webpage
• Type an owner name in the Search DAGs textbox and select it from the dropdown

I can reproduce it on main branch.
I didn't know we can search for owners in "Search DAGs" box? If so then the text in the box needs to be edited.
Choosing owner there indeed doens't work

It raised error:
DAG "airflow" seems to be missing from DagBag.

As a workaround you can filter by using the clicking on owner as added in #11121
it uses /home?search=airflow and filter the DAGs by owner as expected.

I accidentally found we could filter by owner from this textbox on Airflow 2.2.5, where it worked as expected. Thanks for mentioning the workaround!

Yes, in 2.2.5 clicking on an autocompletion match would take you to home-with-search and in 2.3.0 it tries to take you to the matching DAG. Except it's not a DAG. Now if I can just track down the code that does that I can fix it. :)
