@at-root inside Loops will be ignored

[gisu]

Found a Error with @at-root inside Loops.

.container {
  @for $i from 1 through 3 {
    @at-root .box-#{$i} {
      color: darken(red,($i * 5));
    }
  }

 // Control
 @at-root .outside-child {
   background-color: blue;
  }
}

Expected:

.box-1 {
  color: #e60000;
}
.box-2 {
  color: #cc0000;
}
.box-3 {
  color: #b30000;
}
.outside-child {
  background-color: blue;
}

Libsass (in my case the Gulp-Sass 2.0.1 but also tested with Libsass 3.2.5)

.container .box-1 {
  color: #e60000;
}
.container .box-2 {
  color: #cc0000;
}
.container .box-3 {
  color: #b30000;
}
.outside-child {
  background-color: blue;
}

This will be fixed once we release my latest refactoring for parser and at-root, which should have the first beta rounds in a few weeks (if everything goes as planned).

Specs added sass/sass-spec#420

We now have a passing spec test since #1249 was merged 🎈
