When I try to get width and height of the page, I encounter a problem: width and height are misplaced in SOME (but not all!) of the PDFs. The page looks like completely normal A4 portrait document, but using reader.pages[0].mediabox returns wrong dimensions [0, 0, 841.68, 595.2] instead of [0, 0, 595.2, 841.68]

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
# macOS-12.5.1-arm64-arm-64bit
# and also on every system on docker (Ubuntu, CentOS)

$ python -c "import PyPDF2;print(PyPDF2.__version__)"
# 2.10.3

Code + PDF

This is a minimal, complete example that shows the issue:

from PyPDF2 import PdfReader

reader = PdfReader(path)
dimensions = reader.pages[0].mediabox

width = dimensions.width
height = dimensions.height

dim.pdf

I removed sensitive data.
