此throttle函数存储了最后一次触发事件时的参数arguments和context，导致如果后续不再触发此事件，那么上一次触发事件时的dom以及组件都无法被内存回收。 比如在vxe-table中，触发mouse-wheel后表格会被缓存，后面及时销毁了表格，其内存也无法被释放。当然因为mouse-wheel事件是注册在window上的，在空白区域再次滚动鼠标滚轮，内存就会得以释放。

@xuliangzhan 大佬 这个能处理一下吗？今天排查到WheelEvent确实会导致内存溢出 |
@xuliangzhan 大神关注一下这个？ 只是左右滑动，开启了虚拟滚动 vxe-table v3.6.13 PS: 似乎是在keep-alive下会出现 |

怎么解决的，也遇到了同样的问题，不过用的是v 4.5.22版本 |

比如在vxe-table中，触发mouse-wheel后表格会被缓存，后面即使销毁了表格，其内存也无法被释放。当然因为mouse-wheel事件是注册在window上的，在空白区域再次滚动鼠标滚轮，内存就会得以释放，但是新的内容又会被缓存，再关闭另一个表格或者其他组件，内存同样无法被回收。
