And you can swear me the dialog from users-admin is not behaving the same as others?! The only thing users-admin does is asking the backends (so it doesn't even do it by itself) to ask PolicyKit1 to authenticate by whatever means are adequate. So this amounts to "pkcheck --action-id org.freedesktop.systemtoolsbackends.set".
Could you run 'xprop' for each authentication dialog and check that WM_CLASS and _NET_WM_PID are the same for all of them?
