Sometimes passwords are not stored or stored inompletely
This is with gnome-passwordsafe 4.1-1.fc33 on Fedora 33.
I've seen it happen several times now that passwords I entered have not been stored, despite even making sure to press ctrl+s. Usually I only notice this issue a long time after it happens, but this time I needed to access the password right again after entering it.
The password was a generated password that I had edited before saving. The password was only stored up to the last position I edited, i.e. where the cursor was when I saved the database. The password was shown at that time.
