I just reinstalled mate-themes (apt-get install --reinstall mate-themes). This is version 3.22.6-1. When I open the file /usr/share/themes/BlackMATE/gtk-3.0/mate-applications.css at line ~219 it does not contain this line: color: @theme_fg_color; This line was added with one of the above commits. So I can only conclude that the patch isn't included.
