To do:
Convert markdown document to PDF applied style.css

Prerequisites
Pandoc 3.6
wkhtmltopdf 0.12.6

Reproducing:

pandoc source.md -f markdown -o dest.pdf --pdf-engine=wkhtmltopdf

Symptoms:
Pandoc 3.5 worked perfectly.

But, Pandoc 3.6 always failed from 1st step like below.

Error: Failed loading page file://toPC54C.source (sometimes it will work just to ignore this error with --load-error-handling ignore)
Exit with code 1, due to unknown error.
Error producing PDF.`

Unfortunately, --load-error-handling ignore did not help.

Thanks.
