Can't update existing database name - save button disabled

I’m attempting to update the name of an existing database in Metabase. I go to Admin Panel > Databases > (database) and type in a new name, but the Save button remains disabled and can’t be clicked. The save button also seems to remain disabled if I update any other field, such as project ID, dataset ID, etc (this is a BigQuery database).

This issue appears both on Chrome 59.0.3071.109 and on Safari 10.1.1 on MacOS 10.12.5.

It appears the Save button is disabled because a new Auth Code wasn’t entered. Once a new Auth Code is entered, Save becomes enabled.

Not a high priority, but it seems worthwhile to not require a new Auth Code when simply updating the local name of a database.
