The selected element of Radio Component adds z-index: 1

[Hapigs]

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

2.1.4

Environment

macOS Big Sur 11.3.1 Chrome 90.0.4430.212 Vue 2.6.11

Reproduction link

https://github.com/Hapigs/antd-component-demo

Steps to reproduce

1.可在 https://github.com/Hapigs/antd-component-demo 项目中查看
2. 如果 Radio 组件和一个 fixed 元素在重叠时,Radio 选中的的标签会遮挡住这个fixed元素
3.经查看是Radio 组件给选中的标签添加了 z-index: 1, 导致层级过高
4. 如果需要正常显示,需要手动给 fixed 元素设置z-index为1或更大的值来保证层级.

What is expected?

希望去除掉z-index: 1 的样式设置,业务代码不用写z-index来提高层级

What is actually happening?

Radio 组件选中的标签元素层级超过了正常 fixed 的元素
