el-radio-group中， el-radio-button类型 在选项动态变化后，看不到选中状态

[agclqq]

先总结一下问题，目前只发现el-radio-button有问题，el-radio正常。
当el-radio-button的数量动态变化后，is-active的css效果似乎有问题。v-model的数据是正确的。希望尽快修复。

@YunYouJun 能否帮看一下啊，谢谢

[YunYouJun]

你好，我对目前的场景和需要实现的需求有些困惑？
为何需要动态修改选中元素的同时，修改 radio group？

---

使用 computed 动态计算，或许将解决你的问题。

const gradeList = computed(() => xxx)

@YunYouJun 感谢答复！
场景大致是这样的：书本有一些tag信息，这些信息没有像省市县那样的显示的层级关系。当点某个年级时，其他的tag信息会根据年级变化；同样，如果点学科时，年级也可能会变化(假如年级还没选择时)。

并且，目前这个bug出现在了<el-radio-button> ，而<el-radio>符合预期

目前我还没有找到解决办法

我尝试制作了一个 demo，不知道是否与你的需求一致。
