Bug: indentation breaks when AtRules and Rules have different indentation

[kristerkari]

Indentation breaks when formatting this code (it should not change):

.class {
  @for $i from 1 through 10 {
    color: green;

    div {
      color: blue;
    }
  }
  color: white;
}

    expected: |-
      '.class {\n  @for $i from 1 through 10 {\n    color: green;\n\n    div {\n      color: blue;\n    }\n  }\n  color: white;\n}\n'
    actual: |-
      '.class {\n  @for $i from 1 through 10 {\n    color: green;\n\n    div {\n    color: blue;\n    }\n  }\n  color: white;\n}\n'

Everything works correctly if I remove the AtRule:

.class {
  div {
    color: green;

    div {
      color: blue;
    }
  }
  color: white;
}
