screen is flashing while use import html2pdf from 'html2pdf.js' in react

[xLazaki]

I am trying to use

export const downloadPDF = (html, filename) => {
  const style = document.createElement('style')
  style.innerHTML = `
   body {
    position: fixed !important;
    top: -99999px !important;
    left: -99999px !important;
    z-index: -99999 !important;
    }
  `
  document.head.appendChild(style)
  html2pdf().set(
    {
      jsPDF: { format: 'a4', unit: 'mm' },
      image: { type: 'jpeg', quality: 1 },
      margin: -0.1,
    },
  ).from(html).save(filename).finally(() => {
    style.remove()
  })
}

This function prints my HTML. When I call this function, my screen shows the HTML I fixed by rendering it on the outer screen, but it's still showing a white screen before removing the style at the final callback
Does anyone have a solution to solve this problem?
