问题：签名所在的组件已经销毁了，但是resize的时候还是会被监听到是为什么？
组件销毁时在第二张图的83、84行onBeforeUnmount的断点已经触发了，我在下个组件里面resize的时候还是会报如图所示的错误。我并没有使用KeepAlive。
所以我猜想是不是源码中，第二张图中78行和84行添加监听事件和移除监听事件不一致引起的？
onBeforeMount(() => { window.addEventListener("resize", () => { $_resizeHandler(); });});onBeforeUnmount(() => { window.removeEventListener("resize", $_resizeHandler);});

下面是我的代码
