pdf distorted if document changes orientation from page to page

[slowcar]

I have a pdf that changes its orientation, the first page is vertical A4, the next horizontal A4. When using Androids built-in PdfRenderer the document is displayed correctly, but with PdfViewPager the horizontal page is distorted. I suspect that the library does not recognize the orientation change and displays the horizontal page as a vertical one.

Please find attached a simple test pdf and two screenshots to illustrate the issue.
