[timovandeput]

Describe the bug When loading a document with a (90 or 270 degrees) rotated page, the dimensions of the page as reported by PdfPage are not swapped when running on MacOS.

To Reproduce Steps to reproduce the behavior:

1. Load a document containing a rotated page, like e.g. 90-degrees-rotated.pdf.
2. Open first page as a PdfPage.
3. Print the width and height of the page.

Do this on Web and on MacOS native.
