contentWindow of the print Iframe is not loaded.

``First of all, Thanks for your amazing library. I’m currently using react-to-print happily in my project.

But I’m having a problem which is that contentWindow of the print Iframe is not loaded when I try to put some images in my document. Without images, react-to-print works very well.

Below is my screenshot of error message.

I’m using Electron and here is part of my source code with image tags.

  const [objectiveUrl, setObjectiveUrl] = useState<string | undefined>(undefined)

  useEffect(() => {
    const reader = new FileReader()

    reader.onload = () => {
      setObjectiveUrl(reader.result as string)
    }

    if (image instanceof Promise) {
      image.then((_file) => {
        reader.readAsDataURL(_file)
      })
    } else if (image instanceof File || image instanceof Blob) {
      reader.readAsDataURL(image)
    }
  }, [])

  return (
    <Column spacing={10}>
      <img className="objective_pdf_image" src={objectiveUrl} alt="Objective" />
      <div className="objective_pdf_image_title">{title}</div>
    </Column>
  )

1 or 2 images work well, but if there comes more than 2 or 3 images, webContent doesn’t show up.
