SCSS removing space when it shouldn't

[jerelmiller]

Prettier 1.15.3
Playground link

--parser scss

Input:

.result-container {
  @include transition(min-height ($spacer/2) ease-in-out);
}

Output:

.result-container {
  @include transition(min-height($spacer/2) ease-in-out);
}

Expected behavior:

That space between min-height and the math should be left alone. With the space removed, this unfortunately results in some invalid CSS as its now treated as a CSS function instead of the property name. This results in something similar to the the following CSS when compiled by Sass

// Incorrect
.result-container {
  transition: min-height(50px) ease-in-out;
}

I found a similar case:

Prettier 1.19.1
Playground link

--parser scss

Input:

@function dist() {
  @return 10px;
}

div {
  margin: - dist();
}

Output:

@function dist() {
  @return 10px;
}

div {
  margin: -dist();
}

Expected behavior:
The space in - dist() should be preserved. Removing the space causes Sass, in turn, to generate invalid CSS. (SCSS margin: -dist(); generates incorrect CSS: margin: -dist(); instead of correct margin: -10px;.)

AFAICT the latter is resolved, but the original reported issue is not
