How can I render a div that has its visibility:'hidden'? in PDFjs

So I'm implementing a feature in my react web app, and in one of the Views, I have a button that takes 2 HTMLElements and display them in 2 pages in a PDF, but I would like one of them to stay hidden. The problem is that while hidden, PDFjs does not render it. Same happens when trying to set it to position:'absolute' and smth like '-999999px'.

This is the piece of code responsible for capturing and saving:

const downloadIt = () => {
    const blackboard = document.getElementById('blackboard') as HTMLElement;
    const descriptionList = document.getElementById('elementDescriptions') as HTMLElement;
  
    const width = blackboard.offsetWidth;
    const height = blackboard.offsetHeight;
    const aspectRatio = width / height;
  
    html2canvas(blackboard).then((canvas) => {
      const pdf = new jsPDF();
      const imageData = canvas.toDataURL('image/png');
      const pdfHeight = pdf.internal.pageSize.getWidth() * (1 / aspectRatio);
  
      pdf.text(comp.title, 8, 8);
      pdf.addImage(imageData, 'PNG', 15, 15, pdf.internal.pageSize.getWidth() - 20, pdfHeight);
  
      pdf.addPage();
  
      // Add the descriptionList to the PDF
      if (descriptionList) {
        html2canvas(descriptionList).then((descCanvas) => {
          const descData = descCanvas.toDataURL('image/png');
          const descAspectRatio = descCanvas.width / descCanvas.height;
          const descWidth = pdf.internal.pageSize.getWidth() - 190; // Adjust the margins as needed
          const descHeight = descWidth * (1 / descAspectRatio);
  
          pdf.addImage(descData, 'PNG', 15, 15, descWidth, descHeight);
  
          pdf.save(`${comp.title}.pdf`);
        });
      } else {
        pdf.save(`${comp.title}.pdf`);
      }
    });
  };
  

The one I'd like to hide is the one called descriptionList, just a simple div with some Cards inside.

I've tried moving it out of the way, but it keeps giving me an error of corrupt PNG file passed to PDFjs
