Prettier can't parse css transition property when it's too long

Prettier 1.18.2
Playground link

--parser scss
--print-width 100
--single-quote

Input:

.foo {
  &__bar {
    transition: flex 0.3s ease-in-out 0.1s, margin-left 0.3s ease-in-out 0.1s, opacity 0.1s ease-in-out 0.1s;
  }
}

Output:

.foo {
  &__bar {
    transition: flex 0.3s ease-in-out 0.1s, margin-left 0.3s ease-in-out 0.1s,
      opacity 0.1s ease-in-out 0.1s;
  }
}

Expected behavior:

Maybe something like this?

.foo {
  &__bar {
    transition: flex 0.3s ease-in-out 0.1s, 
      margin-left 0.3s ease-in-out 0.1s,
      opacity 0.1s ease-in-out 0.1s;
  }
}

Start by reproducing the Playground example with the scss parser, 100-character print width, and the shown transition declaration. Done means the formatter produces the expected wrapping, including breaks after each transition item as shown.
