Since there are no PHP hooks running on the page, Gutenberg uses a little trick. It runs the add_meta_boxes and add_meta_boxes_{post post_type} hooks in admin_head so that developers can register the meta boxes. In admin_head the PHP code still works normally. Therefore, developers can register the meta box without any problem.
