Commented Unassigned: PDF is corrupted [9116]

Please, I'm trying to convert a PDF file using the simplest implementation of HTML:
```
Dim outputDocument = PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.A4)
```
However, the PDF file is generated with failures.

I'm sending the source html attached.

Thank you very much.
