当rpx后面有!important属性后，build时无法被编译成px（字节跳动小程序）

[LGY-color]

字节跳动小程序iPhone6 发现
代码写得css
.sunsin_width {
width: 160rpx !important;
height: 160rpx !important;
line-height: 160rpx !important;
}
build以后用调试工具查看的css
.sunsin_width {
width: 160rpx !important;
height: 160rpx !important;
line-height: 160rpx !important;
}
预期正常css
.sunsin_width {
width: 80px !important;
height: 80px !important;
line-height: 80px !important;
}
