The "Log In" link at https://build.suse.de/ works as expected, i.e.:

1. the login dialog is displayed
2. username is pre-filled in
3. password is pre-filled in (but with dark circles instead of letters)

All good.

However, the password field pre-filling breaks (no password pre-fill) when I do
the following steps:

* browse to https://build.suse.de/package/show/home:smithfarm/ceph
* click on "Log In", but do not log in - note that password field of login
dialog is pre-filled
* click on "Download package"
* click on "Back" button in browser
* click on "Log In" - password field is empty

This is with Mozilla Firefox. I tried briefly with Chromium, but could not get
Chromium to remember the username and password at all.
