I have a :not css selector in SASS mixin but it doesn't do anything:
Code Snippet:
@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
    }
  }
}
The .notip class is being generated but no CSS is being generated for :not(.notip).
