--parser babel

Input:

styled((props) => {
  return <div {...props}>Thanks for all your hard work</div>
})`
  text-align: left;
  transform: ${() => 'translateX'}(100%);
`

Output:

styled((props) => {
  return <div {...props}>Thanks for all your hard work</div>;
})`
  text-align: left;
  transform: ${() => "translateX"} (100%);
`;

Expected behavior:

styled((props) => {
  return <div {...props}>Thanks for all your hard work</div>;
})`
  text-align: left;
  transform: ${() => "translateX"}(100%);
`;

There shouldn't be a space between translateX and (100%)
