Should be an error when @debug, @warn, and @error are nested beneath properties

[andrew-skybound]

Input:

a {
    margin: {
        @debug test;
        left: 0px;
    }
}

Ruby SASS Output (3.4.19)

Error: Illegal nesting: Only properties may be nested beneath properties.

Libsass Output (3.2.5)

a {
  margin-left: 0px; }

(Console)

DEBUG: test

Same issue with @warn and @error when they are nested beneath properties.

Thanks for the report @andrew-skybound

Spec added sass/sass-spec#618

[andrew-skybound]

Note that when @debug, @warn, or @error appear in a mixin which is included in a nested property scope, no error should be raised (the rules work as they normally would).

@mixin font-properties() {
    weight: bold;
    @warn "Warning";
}

a {
    font: {
        @include font-properties();
    }
}

Output:

WARNING: Warning
         on line 3 of test.scss, in `font-properties'
         from line 8 of test.scss
