<div>
  <p>Whitespace in link and before comma (not desirable)</p>

  <a href="">
    Foo
  </a>
  ,

  <a href="">
    Bar
  </a>

  <hr>

  <p>Whitespace in link but not before comma (still no good)</p>

  <a href="">
    Foo
  </a>,

  <a href="">
    Bar
  </a>

  <hr>

  <p>No whitespace (there we go, but prettier doesn't let us have this)</p>

  <a href="">Foo</a>,
  <a href="">Bar</a>

  <hr>

  <p>Hacky fix (ew! and probably prettier won't let us do this, either)</p>

  <a href="">{{!
    }}Foo{{!
  }}</a>{{!
  }},

  <a href="">{{!
    }}Bar{{!
  }}</a>

  <hr>

  <p>Another hacky fix (ew again! but prettier probably can't mess this up)</p>

  <a href="">
    {{~! remove whitespace plz ~}}
    Foo
    {{~! remove whitespace plz ~}}
  </a>
  {{~! remove whitespace plz ~}}
  ,

  <a href="">
    {{~! remove whitespace plz ~}}
    Bar
    {{~! remove whitespace plz ~}}
  </a>
</div>
