I can't seem to reproduce this. Can you share more details (OS, Go Version, go.mod)

[cuboci]

I seem to have the same problem. Simple setup to reproduce:

This is on Debian Sid with Go version 1.22.3 from official binaries.

go.mod

module markdowntest

go 1.22.3

require (
	github.com/stephenafamo/goldmark-pdf v0.4.1
	github.com/yuin/goldmark v1.7.1
)

require (
	github.com/alecthomas/chroma/v2 v2.10.0 // indirect
	github.com/dlclark/regexp2 v1.10.0 // indirect
	github.com/go-swiss/fonts v0.0.0-20221219152310-0b267088f53d // indirect
	github.com/jellydator/ttlcache/v3 v3.1.0 // indirect
	github.com/phpdave11/gofpdf v1.4.2 // indirect
	golang.org/x/sync v0.1.0 // indirect
)

main.go

package main

import (
	"io"
	"log"
	"os"

	pdf "github.com/stephenafamo/goldmark-pdf"
	"github.com/yuin/goldmark"
	"github.com/yuin/goldmark/extension"
	"github.com/yuin/goldmark/renderer/html"
)

func main() {
	md := goldmark.New(
		goldmark.WithExtensions(extension.GFM, extension.Table, extension.Typographer, extension.Footnote),
		goldmark.WithRenderer(pdf.New()),
		goldmark.WithRendererOptions(html.WithXHTML()),
	)

	buf, err := io.ReadAll(os.Stdin)
	if err != nil {
		log.Fatal(err)
	}
	if err := md.Convert(buf, os.Stdout); err != nil {
		log.Fatal(err)
	}
}
