This particular case should't be a problem

this warning is fired when there is something like

.exampleClass {
  @include aaa;
  bbb: bbb;
}

which can be fixed by redefining it as

.exampleClass {
  bbb: bbb;
  @include aaa;
}

This is not very nice, since if you are forced to have @include declarations to be the last ones, then the styles they bring in can not be overwritten.

that's why you can also fix it by declaring it as

.exampleClass {
  @include aaa;

  & {
    bbb: bbb;
  }
}
