 Scrollbar sizes are different on different platforms. But it seems that
 there are ways to split the Linux users into different buckets based on
 that: On a Debian Stretch system with XFCE I get 15px thickness on an
 Ubuntu 14.04 system with GNOME I get 13px thickness.

 A test can be found on
 http://www.hackerfactor.com/blog/index.php?/archives/761-Exploiting-the-
 TOR-Browser.html.

 One option mentioned in that blog post would be to provide 17px on all
 platforms.
