Exporting the full page as PDF (single page)

Rod Version: v0.114.8

Is there a way for me to be able to export the page as a PDF with only a single PDF page?

So far I've tried modifying the viewport, and setting the paper height:

Modifying the viewport appears to make no difference to the PDF
Increasing the PaperHeight does increase the size of the PDF page, however, it does not increase the content (just adds white space above and below)

Example:

    page := browser.Context(ctx).MustPage()
    err := page.SetViewport(&proto.EmulationSetDeviceMetricsOverride{
        Width:  2000,
        Height: 3000,
    })
    _ = proto.EmulationSetEmulatedMedia{
        Media:    "print",
        Features: []*proto.EmulationMediaFeature{},
    }.Call(page)

    // Dynamically determine the content height
    res := page.MustEval(`() => document.body.scrollHeight`)
    if err != nil {
        return err
    }

    contentHeight := res.Num()

    // Convert the content height to inches for PDF generation (assuming 96 DPI)
    paperHeightInches := contentHeight / 96

    marginTop := 0.0
    marginBottom := 0.0
    marginLeft := 0.0
    marginRight := 0.0

    // Generate the PDF with dynamic dimensions
    reportPdf, err := page.PDF(&proto.PagePrintToPDF{
        MarginTop:       &marginTop,
        MarginBottom:    &marginBottom,
        MarginLeft:      &marginLeft,
        MarginRight:     &marginRight,
        PrintBackground: true,
        PaperHeight:     &paperHeightInches, // Convert pixels to inches for PDF generation
        PageRanges:      "1-1",              // Ensure all pages are included
        //PreferCSSPageSize: true,
    })
    if err != nil {
        return err
    }

    bin, err := afero.ReadAll(reportPdf)
    err = afero.WriteFile(fs, "report.pdf", bin, 0644)

This is something I am able to achieve in Puppeteer:

    await page.setViewport({width: 2000, height: 3000});
      const pdfOptions : PDFOptions = {
          printBackground: true,
          height: `${height} px`,
          width: `${width} px`,
          scale,
          pageRanges: "1"
      };
