InputItem中银行卡格式的光标在UC浏览器中的错位问题

[forest82]

ant-design-mobile版本：1.7.2
目前测了安卓7、8
UC版本：V11.9.3.973(最新)

问题描述：

根据银行卡格式，四个数字空一位，目前光标输到第五位数字，开始错位（之后输入的内容，均出现在光标之前），原因应该是光标识别不了空格。

Misplaced cursor in bank card format in InputItem in UC Browser

ant-design-mobile version:1.7.2
Currently measured Android 7,8
UC version: V11.9.3.973 (latest)

Problem Description:

According to the bank card format, four digits are empty, and the current cursor is entered in the fifth digit, and the position is misplaced (after the input content, both appear before the cursor). The reason is that the cursor cannot recognize the space.
