There are few cases where this might fail, specifically around \@at-rules.

Related test case:

var sample =`
div, h1 {
  span {
    font-size: 14px;
  }
  background-color: rebeccapurple;
}

@media {
  .other-class {
    margin: 20px;
  }
}

@keyframe {
  0%: {color: red}
}

That said i think something like following should handle all of them.

function extraScopePlugin (context, content, selector, parents, line, column, length, type) {
  if (context === 2 && type !== 107)
    for (var i = 0; i < selector.length; i++)
      selector[i] = '#body ' + selector[i]
}

Thanks for the feedback! Haven't figured out that I could just mutate selectors array. Way easier that way 👍
