Double whitespace after var() and before +/- operator inside calc() with disabled minification

[egeesin]

Tried to reproduce that in the Playground as seen in the image below: Disabled "Minify" and chose the latest version (1.22.1).

Wanted to check after awhile and the issue still persists in 1.30.2.

:root{
  --test: 7px;
}
.test{
  width: calc(var(--test) + 2px);
  width: calc(2px + var(--test));
  width: calc(var(--test) - 2px);
  width: calc(2px - var(--test));
}
