taro-ui 3.0.0-alpha.3 AtInput快速输入时会回退

**问题描述**
taro-ui 3.0.0-alpha.3 AtInput快速输入时会回退

**复现步骤**
1、在输入框快速输入数字，例如123456645，这时候输入框有可能只会显示1234645。
2、在输入框长按删除，例如123456645，删除到12345，这时候输入框的文字会回退到123456

```js
const [addressData, setAddressData] = useState({
city: "深圳市",
cityId: 440300,
contact: "",
detailAddress: "",
mobile: "",
province: "广东省",
provinceId: 440000,
region: "宝安区",
regionId: 440306,
isDefault: false,
});

const inputChange = (value, name) => {
const obj = {};
obj[name] = value;
console.log(value, name);
setAddressData({ ...addressData, ...obj });
};

{
inputChange(value, "contact");
}}
/>

```

**期望行为**
期望连续输入或删除时，不会回退
