Comment:

 Replying to [comment:1 swissspidy]:
 > `wp_authenticate_username_password` runs on priority 20, so I guess this
 happens because the function does not immediately return `$user` if it's a
 `WP_Error`.

 That makes sense.

 Since most other filter and action hooks work as expected more-or-less
 irrespective of priority in relation to core functionality, I would
 suggest at minimum that the documentation be updated to reflect the need
 for a priority of 20+ in order to prevent logins. As you know, the default
 is 10.
