set404Override - setLocale not working?

Hi!

I'm just wondering why the controller set in set404Override() not listening to the selected locale. Is this a feature or a bug?
Any other controller is working properly.

app/Config/Routes.php

PHP Code:

$routes->set404Override('App\Controllers\Error::error_404'); 


app/Controllers/Error.php

PHP Code:

<?php namespace App\Controllers;
 
class Error extends BaseController {
  public function error_404() {
    echo $this->request->getLocale(); //Output: no (Norwegian)
 
    echo view('_includes/header_clean'); // Outputs data from en (English)
    echo view('main/main');              // Outputs data from en (English)
    echo view('_includes/footer_clean'); // Outputs data from en (English)
 
    echo $this->request->getLocale(); //Output: no (Norwegian)
  }
}
