annotation coordinates are wrong
Forwarding from https://gitlab.gnome.org/GNOME/evince/issues/1155 because I can reproduce this issue with the poppler-glib-demo program from poppler.
On page 6 of the attached document, 2019_05_02_Classific_annotated.pdf, a text annotation appears near the top of the page, but you need to click near the left hand side of the page to open it. Image shows these locations.
I can get a similar effect by adding an annotation through poppler's poppler-glib-demo program. I add an annotation and it shows up not where I clicked, but somewhere else.
Okular appears to be unaffected by this issue.
