const centered = (triggerRect, tooltipRect) => {
  const triggerCenter = triggerRect.left + triggerRect.width / 2;
  const left = triggerCenter - tooltipRect.width / 2;
  const maxLeft = window.innerWidth - tooltipRect.width - getScrollbarOffset();
  return {

    top: triggerRect.bottom + 8 + window.scrollY
