When an interpolated class is used first in a list, it's ignored

[Cactusbone]

To reproduce:

formGroupClass = ".form-group"

{formGroupClass}
.checkbox
    position relative

Current behavior:

.checkbox {
  position: relative;
}

Expected behavior:

.form-group,
.checkbox {
  position: relative;
}

Workaround 1:

formGroupClass = ".form-group"

.checkbox
{formGroupClass}
    position relative

Workaround 2:

formGroupClass = ".form-group"

{formGroupClass},
.checkbox
    position relative

Environment information:

Another fix is adding a comma: {formGroupClass},

Yep, I've added it as workaround 2 :)
