Airflow UI ignoring extra connection field during test connection

[genehynson]

Apache Airflow version

Other Airflow 2 version (please specify below)

What happened

In Airflow 2.6.1 I can no longer use the extra field in any http based connection when testing the connection.

Inspecting the web request for testing the connection I see that the extra field is empty, even though I have data in there:

{
  "connection_id": "",
  "conn_type": "http",
  "extra": "{}"
}

I saw this issue which seems related. It was closed because the opener worked around the issue by creating the connection in code instead of the Airflow UI.

I couldn't find any other issues mentioning this problem.

What you think should happen instead

The extra field should be included in the test connection request.

How to reproduce

Create an http connection in the Airflow UI using at least version 2.6.1. Put any value in the extra field and test the connection while inspecting the network request. Notice that the extra field value is not supplied in the request.

Anything else

If I had to guess, I think it might be related to this PR where a json linter was added to the extra field.

Saving the connection seems to work fine, just not testing it.
