自定义预览操作栏时，如果外层使用image-preview-group组件，自定义预览操作栏会失败

[guzily]

这是文档中自定义预览操作栏的方法

<template>
  <a-image
    width="200"
    src="https://p1-arco.byteimg.com/tos-cn-i-uwbnlip3yd/a8c8cdb109cb051163646151a4a5083b.png~tplv-uwbnlip3yd-webp.webp"
    :preview-props="{
      actionsLayout: ['rotateRight', 'zoomIn', 'zoomOut'],
    }"
  >
    <template #preview-actions>
      <a-image-preview-action name="下载" @click="download"><icon-download /></a-image-preview-action>
    </template>
  </a-image>
</template>

以下是我的代码，我需要在图片组中使用自定义预览操作栏时，自定义的下载按钮无法显示

<template>
 <a-image-preview-group infinite>
  <a-image
    width="200"
    src="https://p1-arco.byteimg.com/tos-cn-i-uwbnlip3yd/a8c8cdb109cb051163646151a4a5083b.png~tplv-uwbnlip3yd-webp.webp"
    :preview-props="{
      actionsLayout: ['rotateRight', 'zoomIn', 'zoomOut'],
    }"
  >
    <template #preview-actions>
      <a-image-preview-action name="下载" @click="download"><icon-download /></a-image-preview-action>
    </template>
  </a-image>
 <a-image-preview-group infinite>
</template>

请问有在图片组中自定义预览操作栏的办法吗？
