Event sounds missing from Appearance dialog

I see the section is still in the xml
https://gitlab.xfce.org/xfce/xfce4-settings/-/blob/master/dialogs/appearance-settings/appearance-dialog.glade#L664

but its missing from xfce-test built a week ago.

There was commit 55bbc253 by @ochosi to remove the toolbar and presume the bug was introduced there as there is no other significant patch in the last 6 months.
