[Bug Report] el-radio，点击选择框时，控制台报Blocked aria-hidden on ......

### Element UI version
2.15.14

### OS/Browsers version
chrome

### Vue version
2.7.16

### Reproduction Link
https://element.eleme.cn/2.15/#/zh-CN/component/radio

### Steps to reproduce
点击任意一个选择框，控制台报
Blocked aria-hidden on a element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.

### What is Expected?
看了一下代码，是因为在radio.js文件加了"aria-hidden": "true"这么一个属性
不影响实际使用。网上搜了一圈，发现没有人提到这个现象，所以提一下

### What is actually happening?
无
