I'm using the exclude option of Lightning CSS. According to the documentation:

The include and exclude options allow you to explicitly turn on or off certain features.

Adding MediaRangeSyntax to exclude turns out not to work:

• input:

@media (min-resolution: 2dppx) {
  .a {
    color: green;
  }
}

• current output:

@media (resolution>=2dppx){.a{color:green}}

• expected output:

@media (min-resolution: 2dppx){.a{color:green}}
