Can [Feature Request] let el-pagination implement popper-append-to-body attribute functions similar to those in el-select

### Existing Component
是

### Component Name
el-pagination

### Description
可否让 el-pagination 实现类似el-select 当中的 popper-append-to-body 属性功能，因为有时候分页组件会用在hover弹出页中，如果能实现 popper-append-to-body=‘false’，选择页大小时hover弹出页不会被隐藏
