Thanks for the PR, but the reproduction doesn't make sense.

<KeepAlive>
    <Test1 v-if=\"flag\" :key=\"key\" />
    <Test2 v-else :key=\"key\" />
  </KeepAlive>

If the keys of if/else are different, there will be no issue.

是的，这个例子是为了复现这个问题特意写的，实际情况下目前除了这样也几乎无法复现这个问题，但传给 patch 的 parentComponent 参数确实错了，主要是目前 patch 基本只在 mount 和 unmount 时使用到了 parentComponent，如果后续代码迭代中 patch 对传入的 parentComponent 有其它的使用方式就有可能会出现问题
