I can edit them with Kate, but cannot rename, move, create folders, or set permissions. No authorization pop up occurs, simply an permissions error message. This is clearly a bug as Dolphin plainly states that it will not run as su, but authorize individual actions instead. Currently using an alternative manager with considerable frustration. Expletives withheld at some effort.
It's work in progress, see https://phabricator.kde.org/T6561
