Prompts for root password on user log-in after upgrade from Fedora 26 to 27

edit

Since I upgraded my system a few weeks ago from Fedora 26 to Fedora 27, whenever I log in to my (unprivileged) user account I get the following two prompts:

Authentication Required / Configuring networking requires privileges / Administrator / Password:

and

Authentication Required / Setting RfKill state requires privileges / Administrator / Password:

I hit the Cancel button on both prompts and my session runs normally (with networking working fine), but it is annoying to get the unnecessary prompts.

Have I done something wrong during the upgrade? And is there a way to get rid of the prompts?
