box-shadow property not respecting strict unary operator with 0

[mikokofuyu]

I have the following sass code. I believe this issue is related to: https://sass-lang.com/documentation/breaking-changes/strict-unary/

box-shadow:  0px (-1px) 12px #fff;

When I am compiling this sass file it's output is the following

box-shadow:  0-1px 12px #fff;

However when I use any other px value other than 0, for example:

box-shadow:  2px (-1px) 12px #fff;

compiles to the following expected value:

box-shadow:  2px -1px 12px #fff;
