Following the fix in T164583, there are many confusing options. This should probably have closed options (compatible with constraints?) as it isn't quite clear what to fill there. If you write "noun" it suggest too many non relevant options (such as Noun (Q2445359)). The description is not displayed, which make it even more confusing.
