QuerySelector : infinite loop when there is no number before n

[takaya1992]

Describe the bug

infinite loop when there is no number before n on nth-child

for example: :nth-cihld(n+2)

To Reproduce

window = new Window();
document = window.document;
const container = document.createElement('div');
container.innerHTML = `
  <div>
    <span>a</span>
    <span>b</span>
    <span>c</span>
  </div>
`;
const elements = container.querySelectorAll(':nth-child(n+2)'); // inifinite loop
// Expected : [ '<span>b</span>', '<span>c</span>' ]

Expected behavior

return the expected value without going into an infinite loop
