wrong text order in paragraph

[mieslep]

Bug

A challenging PDF has a very complicated object layer/construction and on page 7 are a number of paragraphs like this, all of which are rendered in the wrong order:

Steps to reproduce

converter = DocumentConverter()
result = converter.convert("https://avys.omu.edu.tr/storage/app/public/seden.dogan/129943/tour%20book%20India.pdf")
doc = result.document

print(doc.export_to_markdown(page_no=7))

Note this text:

, the open air art gallery of Rajasthan, is a quaint village in the heart of Shekhawati region. Mandawa has preserved fine examples of frescoes and painted havelis, as masterpieces of art from bygone era. MANDAWA

But it should be:

MANDAWA, the open air art gallery of Rajasthan, is a quaint village in the heart of Shekhawati region. Mandawa has preserved fine examples of frescoes and painted havelis, as masterpieces of art from bygone era.

The "MANDAWA" is at the end of the line, rather than at the front.

Using (default) OCR does not resolve the problem:

converter = DocumentConverter(
    format_options={
        InputFormat.PDF: PdfFormatOption(
            pipeline_options=PdfPipelineOptions(
                do_ocr=True,
                force_full_page_ocr=True,  
            )
        )
    }
)
result = converter.convert("https://avys.omu.edu.tr/storage/app/public/seden.dogan/129943/tour%20book%20India.pdf")
