I was mistaken about the new grammar breaking the test (it just
made it visible). Replacing it with:

  =-=
  const foo = (props) => {
  return (
  <div>
  <div>
  <div>
  <div>
  {
  props.foo
  ? Hello, foo!
  : Hello, World!;
  }
  </div>
  </div>
  </div>
  </div>
  );
  }
  =-=
  const foo = (props) => {
    return (
      <div>
        <div>
          <div>
            <div>
              {
                props.foo
                  ? Hello, foo!
                  : Hello, World!;
              }
            </div>
          </div>
        </div>
      </div>
    );
  }
  =-=-=

and running with older grammars (0.19,20,21) also fails.
