React项目引入react-datepicker CSS报CssSyntaxError，疑与Stylus解析器有关

• 项目使用工具及版本：PostCSS 8.4.21、Stylus 0.59.0、Stylelint 15.2.0
• 问题表现：引入react-datepicker的CSS文件时触发CssSyntaxError: Unclosed bracket编译错误；注释掉包含多参数:not()选择器的CSS代码段后，项目可正常编译
• 经定位，引发错误的CSS代码（语法本身合法）如下：

range:not(.react-datepicker_day--in-selecting-range,
.react-datepicker__month-text--in-selecting-range,
.react-datepicker__quarter-text--in-selecting-range,
.react-datepicker__year-text--in-selecting-range),
.react-datepicker_month--selecting-range .react-datepickermonth-text--in-range:not(.react-datepicker_day--in-selecting-range,
.react-datepicker__month-text--in-selecting-range,
.react-datepicker__quarter-text--in-selecting-range,
.react-datepicker__year-text--in-selecting-range),
.react-datepicker_month--selecting-range .react-datepickeryear-text--in-range:not(.react-datepickerday--in-selecting-range,.react-datepickermonth-text--in-selecting-range,.react-datepickerquarter-text--in-selecting-range,.react-datepicker_year-text--in-selecting-range) {
  background-color: #f0f0f0;
  color: #000;
}
