Text missing from PDF with large ratio

[LuRe97]

Bug

I am testing various pdf files in order to be able to improve the solution I am building on top of docling. I came across a weirdly ratioed pdf that was taken from a website. When loaded with docling it omits a lot of characters that should be accessible through raw text. I attached the file to this issue, when loading this specific file via other libraries like e.g. PyPDF everything works as intended.

Problematic PDF:
Baldur's Gate III Guide - IGN (1).pdf

PyPDF Parsing Output:
PyPDF_Parsing_Output.txt

Docling Parsing Output:
Docling_Parsing_Output.txt

Steps to reproduce

Run the basic example with the problematic pdf
from docling.document_converter import DocumentConverter

source = "Baldur.s.Gate.III.Guide.-.IGN.1.pdf"
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown())

This is an edge case docling is currently not working well with. Super tall pages such as in the provided PDF will cause limitations in image resolution seen by the layout detection model, and results can be unpredictable. The PDF looks like a printed website. You could try to feed the HTML version to docling for better results.
