Comment:

 I believe this is ultimately caused by this call to wp_signon() with an
 empty array of credentials: https://github.com/WordPress/wordpress-
 develop/blob/4912e0107dddbc34bdac71a1a7bc9f8e21335742/src/wp-
 login.php#L1233.

 Inside `wp_signon()` the `user_login` and `user_password` elements are
 implicitly set to null here: https://github.com/WordPress/wordpress-
 develop/blob/4912e0107dddbc34bdac71a1a7bc9f8e21335742/src/wp-
 includes/user.php#L67 and these null values propagate down to
 `preg_replace()` and `trim()`.
