`global-display-fill-column-indicator-mode` should definitely belong to
the `display-fill-column-indicator` group (because the `defcustom`
doesn't have an explicit `:group` so it should fallback to using the
last-defined group).

BTW, another quick-fix might be to move the defface definition to
display-fill-column-indicator.el.
