Please be aware that you are using FlyingSaucer, not iText.
FlyingSaucer is a product that internally uses (a very old version of) iText.
You are immediately cutting yourself off from 10+ years of bugfixes and developments.
If you are comfortable going for just iText, the best way of solving this issue is with pdfHTML.
It's an add-on we wrote to the iText7 core library that is specifically designed to convert HTML into PDF.
Simple example:
File src = new File("source_html_file.html");
File dest = new File("target_pdf_file.pdf");
PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdf, PageSize.A4);
InputStream stream = new FileInputStream(src);
ConverterProperties converterProperties = new ConverterProperties();
FontProvider dfp = new DefaultFontProvider(true, true, true);
converterProperties.setFontProvider(dfp);
HtmlConverter.convertToPdf(stream, pdf, converterProperties);
