Description
问题表现同 #276
问题描述: 比如存在formatter函数时(见下面地址), 当输入1234时，期待显示$1,234， 但是实际显示$12,344
复现地址：http://react-component.github.io/input-number/examples?path=/story/rc-input-number--formatter
复现的环境： windows10, chrome浏览器版本号：87.0.4280.88， 微软拼音输入法切换到中文输入状态。
进一步研究源码发现，当存在formatter属性并且formatter返回一个新的值时，会触发onChange函数两次。
firefox表现正常，只会触发onChange一次。
中文其他输入法(如qq拼音输入法)没有问题，微软拼音输入法英文状态也没有问题。
mac下表现正常。

Research direction
Start with the formatter example at the linked rc-input-number Storybook URL and reproduce it on Windows 10 with Chrome and Microsoft Pinyin in Chinese mode. Trace the formatter and onChange handling to determine why entering 1234 produces $12,344 and fires onChange twice; done means the display is $1,234 and onChange fires once, while Firefox and unaffected input methods remain working.
