Pseudo-classes are no longer correctly scoped

[smlombardi]

In VSCode insiders, in a nested item like this:

.dropdown-item {
  padding: 10px 30px 5px 20px;
  color: $gray-500;
  white-space: nowrap;
  font-family: $font-family-sans-serif;

  &:hover {
    background-color: $gray-60;
  }

  &:active, &.active {
    background-color: $gray-60;
    color: $gray-500;
  }

  &:last-child {
    padding-bottom: 10px;
  }

  &.disabled {
    color: $gray-300;
  }
}

The &:hover is not correctly colored:

the :active is correctly colored

This is a regression, it used to work fine..

I am going to assume this was caused by #234, which was reverted in #238.
