PdfDocument Render doesn't render markup even with PdfRenderFlags.ForPrinting

[milos12345]

I tried using highlight and draw tools from both Edge and Acrobat Reader but the following code doesn't render it. I have expected that

using (var image = pdfDoc.Render(page, w, h, dpi, dpi, PdfRenderFlags.LcdText | PdfRenderFlags.Annotations | PdfRenderFlags.ForPrinting))
{    
    return BitmapHelper.ToBitmapSource(image); 
}

I expected PdfRenderFlags.ForPrinting would show this, because if I try printing document from Acrobat or Edge, these show up
