This looks like an issue with poppler since evince is also affected.

Thanks @aikrahguzar

I adapted the issue description and forwarded it to https://gitlab.freedesktop.org/poppler/poppler/-/issues/1435

More precisely, it could be an issue with poppler-glib since okular is not affected and the poppler-glib-demo is.
