Fixed a bug in Paragraph.AppendHyperlink(h) that caused any custom formatting to be applied to the runs before the Hyperlink instead of the Hyperlink itself. The below is now possible
Paragraph p = document.InsertParagraph();
p.Append("Check out this ").Color(Color.Red).AppendHyperlink(h).Color(Color.Green).Append(", it's really cool").Color(Color.Blue);
