Comment (by gma992):

 Replying to [comment:9 westonruter]:
 > This is a good first bug to get feet wet with customizer JS API. There
 is already a notification that displays when there are no widget areas in
 the preview, so the needed patch would extend that to show another
 notification when there are some widget areas sections that are not
 active.

 I'm trying to get that notification to show up using a custom page without
 widget areas but I'm unable to see it (shows up for a second when the
 customizer loads but disappears immediately), examples:

 - Custom page with zero widget areas: https://cloudup.com/caQZhxkb4jf
 - If I get rid of one of them only (the sidebar widget area) it shows
 correctly the remaining two: https://cloudup.com/cSdT5Zxz4cp

 Maybe I'm misunderstanding the expected behavior?

 If I'm on the right path we're looking at `src/wp-admin/js/customize-
 widgets.js`, and the notification that should trigger when there are no
 widget areas in the preview is:

 {{{
 'noAreasRendered'  => __( 'There are no widget areas currently rendered in
 the preview. Navigate in the preview to a template that makes use of a
 widget area in order to access its widgets here.' ),
 }}}
