PDF annotations not shown when diffing PDFs with diffoscope.
Diffoscope doesn't show PDF annotations when diffing PDFs. I created a number of comments in both evince and okular. Only two types of comment ("inline note" and "typewriter annotation" and from Okular) shows up in the diff. I have attached two example files that are identical apart from their comments.
I used the docker image on the website to test this to ensure I had the most recent release (hopefully):
$ docker run --rm -t -w $(pwd) -v $(pwd):$(pwd):ro registry.salsa.debian.org/reproducible-builds/diffoscope test_pdf.pdf test_pdf_commented.pdf
--- test_pdf.pdf
+++ test_pdf_commented.pdf
