Conflict with User Switching plugin

Testing this plugin on a site with the User Switching plugin installed throws the following error when visiting a link with the autologin enabled:

2024/02/18 06:14:04 [error] 39262#39262: *32635 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Undefined constant "USER_SWITCHING_SECURE_COOKIE" in /www/public/wp-content/plugins/user-switching/user-switching.php:1356

I patched the /src/wp-includes/class-login.php file with a small patch below within the process method that solves the issue in the short term.

// Compatibility with User Switching plugin.
if ( function_exists( 'user_switching_get_auth_cookie' ) && ! defined( 'USER_SWITCHING_SECURE_COOKIE' ) ) {
    define( 'USER_SWITCHING_SECURE_COOKIE', false );
    }
