If possible, the search suggestions showing special page aliases in Russian shouldn't display. If not – they should be deprioritized, so that the search suggestions would appear in Ukrainian first. This is per T39314
Now if one tries to search for special pages starting with "У", one gets 6 suggestions in Russian, 2 in Ukrainian and 2 more in Russian, respectfully. Anyway, a Ukrainian wiki should display special page names suggestions in Ukrainian first. I think this is obvious.
Russian fallback is being removed from ukwiki, and special pages aliases had to be gone too, but the devs decided to keep them for backwards compatibility (essentially they shouldn't appear anywhere in ukwiki unless they're used somewhere in the wikitext). That's why we're requesting to remove them from suggestions.
Can this be done?
