bug#29711: 25.2; mode-line distortion when using :box on mac os

[Adam Simpson]

1. Paste and then evaluate the following in the *scratch* buffer:
(set-face-attribute 'mode-line nil
                    :foreground "white"
                    :background "red" 
                    :box '(:line-width 5 :color "red"))
(setq-default mode-line-format (list 
              '(:eval mode-line-position)
              mode-line-modes))
2. Open a long file that has thousands of lines. I used ivy.el which is
around 4k lines.

3. Observe the mode-line is "distorted" like so: https://i.imgur.com/qxAsdfm.png
