我正在尝试使用服务器端渲染创建古腾堡块。问题是块渲染在左上角。在前端，它按预期显示。

const { __ } = wp.i18n;
const { registerBlockType } = wp.blocks;
const el = wp.element.createElement;


registerBlockType( \'wda-wda/wda-gutenberg-block\', {
    title: __( \'My Block\', \'wda-wda\' ),
    icon: \'admin-users\',
    category: \'common\',
    attributes: {
        images : {
            default: [],
            type:   \'array\',

        }
    },
    edit( { attributes, setAttributes, className, focus, id } ) {
        // Put a user interface here.
        return null;

    },
    save( { attributes, className } ) {
        // Gutenberg will save attributes we can use in server-side callback
       return null;
    },
} );

function wda_register_block() {

    register_block_type( \'wda-wda/wda-gutenberg-block\', array(
        \'editor_script\'     => \'wda-gutenberg-block\',
        \'render_callback\'   => array( $this, \'render_callback\' ),
    ) );
}

function render_callback() {
    echo \'The Content\';
}
add_action( \'init\', \'wda_register_block\');

是否应手动调整？
