Cannot handle nested calc()? #49
Description
Using reduce-css-calc via cssnano via optimize-cssnano-plugin.
The input CSS I believe is coming from Bootstrap 4, possibly this line, but it's hard to pinpoint based on the error.
height: calc(calc(2.25rem + 2px) - 1px * 2);
Getting:
ERROR Error: CSS minification error: Parse error on line 1:
auto - 1px * 2
