An issue was discovered in certain configurations of GNOME gnome-shell
through 3.36.4. When logging out of an account, the password box from the
login dialog reappears with the password still visible. If the user had
decided to have the password shown in cleartext at login time, it is then
visible for a brief moment upon a logout. (If the password were never shown
in cleartext, only the password length is revealed.)
