var clone_data = document.querySelector('.clone-dom #contentToConvert');

html2canvas(clone_data, {
    scale: 1, 
    width: 1700,
    height: 2125,

I'm creating HTML to PDF using this package. The HTML preview is perfect as expected on all devices Mac and Windows. But when I make PDF everything goes smoothly on Windows on all browsers. But on Mac, I face some issues related to image placement (zoomed and not positioned centered as it is previewed). On Safari the image is not displayed. Following are the CSS styles that are being applied.

export const ImageWrapper = styled.div`
  width: 100%;
  height: 100%;
  overflow: hidden;
  position: relative;
  aspect-ratio: 1 / 1;
  margin-bottom: 20px;

  img {
    position: absolute;
    width: 100%;
    height: auto;
  }
`;

Please let me know how can I fix this issue.
