Subject: 26.3; Whitespace Newline Face Doesn't Disappear
-----

When typing at the bottom of a document, a newline is inserted. An
additional newline is then inserted. Upon insertion, a face higlights
the first newline's emptiness. Typing in the second newline should make
this face disappear. However, it remains.

The whitespace configuration (13.2.2):
(use-package whitespace
:ensure t
:init
(setq prelude-whitespace nil)
(setq whitespace-line-column 80)
;; Highlight trailing whitespace
(setq whitespace-style
;; There's a bug in empty where the face doesn't go away after
;; typing below the newline.
'(face trailing lines-tail indentation::space tab-mark empty))
:config
(global-whitespace-mode t))
