DPI doesn't change for new instance #3588
Description
For some reason if I create a second document, the dpi will not change. I takes previously set dpi...
$pdf->getOptions() has the new dpi, but the rendered document has old dpi (100).
$pdf = new Dompdf();
$pdf->set_option('dpi', 100);
$pdf->loadHtml($html);
$pdf->render();
unset($pdf);
$pdf = new Dompdf();
$pdf->set_option('dpi', 200);
$pdf->loadHtml($html);
$pdf->render();
