Preferences: Number of rows slider is longer than Row size and Length
$ xfce4-panel --version xfce4-panel 4.14.3 (Xfce 4.14)
My knowledge of GTK3 is very limited. I tried inspecting
xfce4-panel/panel/panel-preferences-dialog.glade but I can't find a difference that makes the
GtkScale longer than the other 2.
