点击外层的ajax请求，会在调用saveForm之后刷新crud组件，而在操作栏的ajax请求则不会刷新

1. 你是如何使用 amis 的？
npm

2. amis 版本是什么？请先在最新 beta 版本测试问题是否存在
最新版本的1.9.1-beta17都存在这问题

3. 粘贴有问题的完整 `amis schema` 代码：
```
{
"type": "page",
"body": [
{
"type": "button",
"label": "ajax 请求(这里的可以reload crud)",
"actionType": "ajax",
"api": "/amis/api/mock2/form/saveForm",
"reload": "crud"
},
{
"type": "divider"
},
{
"type": "crud",
"name": "crud",
"api": "/amis/api/mock2/sample?waitSeconds=1",
"columns": [
{
"name": "id",
"label": "ID"
},
{
"name": "engine",
"label": "Rendering engine"
},
{
"name": "browser",
"label": "Browser"
},
{
"name": "action",
"label": "操作",
"type": "wrapper",
"fixed": "right",
"body": [
{
"type": "button",
"label": "ajax 请求(放在crud里就不行)",
"actionType": "ajax",
"api": "/amis/api/mock2/form/saveForm",
"reload": "crud"
}
]
}
]
}
]
}
```

4. 操作步骤
分别点击两个ajax请求按钮

Start with the official action example linked in the issue and compare the outer AJAX button with the AJAX button nested in the CRUD column using the supplied schema. Done means both buttons reload the CRUD component after the request succeeds, with the behavior verified against the reproduction steps.
