Comment 1 for bug 1822276

Thank you for your bug report. It seems similar to upstream https://gitlab.gnome.org/GNOME/evince/-/issues/909 but the behaviour should be that it stores in the same directory as the current document by default, or if it's a temp location then fallback to the document directory and it's not there to the user dir
If you wish to discuss the behaviour it's better done on gitlab upstream than on launchpad
