 There are some strings which I could not find (probably not used):

 - `postTypeLabel` - Not used?
 - `taxonomyTermLabel` - Not used?
 - `pendingTitleTpl` - Comment suggests that it is used for items with
 draft status. But I was not able to add any draft item into menu in
 Customizer. It works on menu admin page, but items are not marked anyway.
 - `invalidTitleTpl` - Not sure what does it mean invalid title for menu
 item?
