重现步骤

1、依次打开外部popup和内部popup，此时lock-scroll正常工作
2、关闭两个popup
3、再次打开外部popup，此时lock-scroll失效

期望的结果是什么？

再次打开外部popup时lock-scroll仍然有效

实际的结果是什么？

再次打开外部popup时lock-scroll失效

其他补充信息

目前lock-scroll的锁定和解锁使用了watchEffect，当destroy-on-close为true或者内部有条件渲染的其他popup时会导致外层popup弹出时的锁定操作被内层popup初始化时触发的解锁操作解锁。是否可以改为使用watch替代watchEffect。另外lock-scroll是否需要考虑keep-alive场景下的跳转解锁，比如在keep-alive的页面中popup内部有路由跳转动作，此时不会触发解锁，跳转后的页面无法滚动。

另外请问有什么办法能获取到popup组件的dom引用？
