我已经通过官方create-block 包，然后我从核心块中提取代码column 来自Github。它似乎在处理一些小问题。出于某种原因，我的自定义块得到的元素结构略有不同，其中块父元素嵌套在其自身中：

知道为什么会这样吗？相关代码如下。

index.js

export { metadata, name };

export const settings = {
  title: _x( \'12 Column\', \'block title\' ),
  icon,
  description: __( \'A single column within a columns block.\' ),
  edit,
  save,
  // deprecated,

registerBlockType( \'wav/twelve-column\', settings );
