Beacon doesn't work with mode-icons

[rsbowman]

See this issue: Malabarba/beacon#53. The following init.el file shows the problem, which is that the "beacon" doesn't fade away and disappear. Any help would be appreciated. Thanks!

(require 'package)

(package-initialize)
(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(eval-when-compile
  (require 'use-package))

(use-package mode-icons
  :config  (mode-icons-mode))

(use-package beacon
  :init (beacon-mode t))
