PDF text forms not redering if only /V is present or /AP does not contain text.
When filling in textfields in a acroform without having an /AP field present, i think the expected behavior is to render the context from the /V field, however currently poppler will render an empty field, or when the AP is an empty box it ant the /V has some contents in there it will not render the filled in text.
When running the pdf to the pdfto* tools it does report the following error:
- Syntax Error: Can't get Fields array<0a>
It could be that it is also somewhat a malformed pdf.output.pdf
I have attached a pdf within this format containing some dummy data, both pdfjs and acrobat reader and at least the buildin iOS reader display this behavior of rendering the /V text, and also mupdf works fine.
This was tested with on arch with the latest poppler version (21.01.0), and the pdfs where generated using pypdf2.
