BackgroundArtifact displays background only on two first pages

Hi team,
I need to add same background to all PDF pages.
I’m using BackgroundArtifact class, but bg is drawn only on first two pages and missing on other pages.
TestAsposePdf.pdf (10.2 KB)
TestAsposePdf.zip (5.3 KB)

var doc = new Document();
var page = doc.Pages.Add();

var background = new BackgroundArtifact
{
    BackgroundImage = Assembly.GetExecutingAssembly().GetManifestResourceStream("TestAsposePdf.bg.png"),                 IsBackground = false  };
page.Artifacts.Add(background);
var fragment = new TextFragment(
            "Lorem ipsum dolor sit amet, consectetur adipiscing elit, " +
            "sed do eiusmod tempor incididunt ut labore et dolore magna " +
            "aliqua. Ut enim ad minim veniam, quis nostrud exercitation " +
            "ullamco laboris nisi ut aliquip ex ea commodo consequat. " +
            "Duis aute irure dolor in reprehenderit in voluptate velit esse " +
            "cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat " +
            "cupidatat non proident, sunt in culpa qui officia deserunt " +
            "mollit anim id est laborum.")
{
    TextState = {FontSize = 12, LineSpacing = 6}
};

for (int i = 0; i < 30; i++)
{
    page.Paragraphs.Add(fragment);
}

doc.Save("TestAsposePdf.pdf");
