[Question] Message.show 导出的hide不能把自己清除

```
const hide = Message.show({
type: 'loading',
});
setTimeout(() => {
hide();
Message.show({
content: '11111111',
});
}, 2000);
```

- hide方法并没有将自己的show清除掉

Start by reproducing the provided Message.show example and trace the Message.show and returned hide entry points. Done means calling hide removes its own loading message before the subsequent Message.show call displays new content.
