Placeholder selector inside :not()

[andreev-artem]

Minimal repro:

%not {
  color: red;
}

.not {
  @extend %not;
}

div:not(%not) {
  color: black;
}

CSS output:

.not {
  color: red;
}

div:not(%not) {
  color: black;
}

Expected output:

.not {
  color: red;
}

div:not(.not) {
  color: black;
}

It works as expected using Ruby version.

Thanks for the report @andreev-artem. I can confirm this is an issue in 3.3.2.
