Magento 2.4.7禁用Page Builder时自定义分类WYSIWYG属性无法保存

环境 #

• Magento 2.4.7-p7
• 前端使用Hyvä
• Page Builder已禁用（启用后问题消失，分类SEO描述可正常保存）

目标 #

添加自定义分类属性seo_description，在后台以WYSIWYG形式渲染，且保存后值可持久化（与核心description属性表现一致）。目前字段已正常显示，但点击保存后值无法存储，必须保持Page Builder禁用状态。

已尝试方案 #

• 保留template="ui/form/field"：后台正常显示SEO描述标签，但保存时提交旧值，新输入内容不生效，刷新后字段仍为空/无变化。
• 移除template="ui/form/field"：SEO标签消失（显示效果差），但值可正常保存。
• 启用Page Builder：标签和值均正常工作，说明PB的表单修饰器正确处理了数据绑定。
• 改为纯textarea（无WYSIWYG）：带包装器时值可正常保存，但不符合需求。
• 排查确认：无其他模块/主题的重复配置，无后台对Magento_Ui field.html的重写。
