Reproduction link

https://next.antdv.com/components/auto-complete

Steps to reproduce

在官网上选择带蓝色搜索按钮那个组件（Lookup-Patterns - Uncertain Category），没法正常输入，也没法正常显示提示下拉列表。

What is expected?

正常输入，正常显示下拉列表

What is actually happening?

输入一个中文字，再输入，就会覆盖掉原来的中文字。下拉列表也没有出来。必须点击一下外面，才会显示下拉列表。

auto complete组件只要带这个搜索按钮，以前是可以的。我在本地尝试去掉这个搜索按钮后也是正常的。
