How to set z-index attribute in the image preview container?

[QC2168]

This function solves the problem (这个功能解决的问题)

I use the drawer component and set the z-index to 5000, while I use the image component in the drawer component. However, I encountered a drawer layer level that is higher than the image preview, resulting in the image not being displayed

Expected API (期望的 API)

:z-index="5000"

I tried using deep, but it didn't work

:deep(.n-image-preview-container){
  z-index: 5001 !important;
}

:deep(.n-image-preview-container){
  z-index: 5001 !important;
}

n-image-preview-container元素是跟app同级的，把deep去掉，并且去掉scope就可以了

我在index.css中写入解决了，如果在App.vue上不添加上deep的话，Vue会额外处理类名的 @667-1
