What happened

When creating/editing a Snowflake connection, adding raw JSON to Extras like:

{"account": "1234"}

gets replaced on save by:

{"insecure_mode": false}

If you instead type “Account” in the dedicated Snowflake field and save, the value reappears in Extras on reopen. But entering account directly in Extras is lost/overwritten.

What you think should happen instead

• Saving a connection should not delete/overwrite user-supplied keys entered directly in Extras if they’re valid for the connection type.

How to reproduce

1. Go to Admin → Connections → + (or edit an existing connection).

2. Set Conn Type = Snowflake.

3. In Extras (raw JSON), paste:

   {"account": "1234"}

4. Click Save.

5. Reopen the connection.

Result: Extras now shows:

{"insecure_mode": false}

Your account key is gone.
