bug#42110: Whitespace Newline Face Doesn't Disappear

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))
