Also, if we want to translate the composer control name, we need to fix the core issue.

    public function getPageTypeComposerControlDisplayName($format = 'html')
    {
-        $value = $this->getPageTypeComposerControlName();
+        $value = tc('PageTypeComposerFormLayoutSetControlName', $this->getPageTypeComposerControlName());
        switch ($format) {
            case 'html':
                return h($value);
            case 'text':
            default:
                return $value;
        }
    }
