PdfGenerator scales by 133% (or 1/3)

I'm having issues with getting a page designed to fit on 8.5x11 Letter paper to size/position properly. So I just do a simple html with a div with a set height and width as a sanity check. First I did "width: 1in; height: 2in;" and the resulting div on the PDF was 1.33333 inches x 2.66666 inches. So I tried points of 72pt x 144pt, and the same thing. If I do 54pt x 108pt I get a box that is 1inx2in. So I have to specify sized that are 3/4 the size I really want in order to get the actual on page size I'm looking for apparently.

Is there some scaling going on that you can control? Do I need to do some reset on the body? What is the user.css that it uses. I wasn't able to find these things in the source code.

Here is the simple html I'm testing:

Anyone have any thoughts on this?

No source file or test is named in the issue. Start by reproducing the supplied HTML and measuring the generated PDF dimensions, then trace the PDF-generation path for the reported 133% scaling. Done means CSS inch and point dimensions render at their specified physical size without requiring 3/4-sized values.
