Set this in application_controller.rb:

  def after_sign_out_path_for scope
    root_path
  end

You expect the logout to redirect the user to root.

However Devise returns a redirect with status 302, which does not work with Turbo.

All redirects must return 303 (i.e. status: :see_other) in order to work with Turbo.

This should be fixed in Devise in order to work with Rails 7.
