Orientation.Landscape does not work anymore

[Sicos1977]

In a previous version I could set the pdf page to landscape like this

section.PageSetup.Orientation = Orientation.Landscape;

And that was it...

In the latest version it only works when I also swap the widht and the height like this

(section.PageSetup.PageWidth, section.PageSetup.PageHeight) = (section.PageSetup.PageHeight, section.PageSetup.PageWidth);

Is this by design or is this a unsupported feature?

Is this by design or is this a unsupported feature?

Most likely this is a documented feature, but I cannot tell for sure seeing just a single-line code snippet.
