3. KeepAlive‘s storageContainer still have comp1.element

中文：

1. 点击' show comp2 '按钮显示组件' comp2 '
2. 点击' remove keep-alive comp1 '按钮从keep-alive include中移除' comp1 '
3. KeepAlive的storageContainer还存在comp1的element

What is expected?

storage container remove comp1.element

What is actually happening?

storage container still have comp1.element

一个组件 deactivated 后 ，将其从 KeepAlive的include 中删除，KeepAlive的storageContainer不会删除此组件的element，导致此组件无法回收，造成内存泄漏。

When a component is deactivated, delete it from the KeepAlive include too. But the KeepAlive storageContainer still contains a element of the component, which causes memory leak.
