CKEditor interface language does not use $user->language variable

For me this works:

  if ($conf['auto_lang'] == "f") {
    $settings['language'] = $conf['lang'];
    //
            
              #1473010: [D7] Spell checker set to use interface language →
            
    $settings['scayt_sLang'] = ckeditor_scayt_langcode($conf['lang']);
  }
  ### PATCH START ###
  else {
    $settings['language'] = $language->language;
  }
  ### PATCH END ###
