Steps to replicate the issue (include links if applicable):

• Log in to the Swedish Wiktionary.
• In the Recent Changes preferences ("Senaste ändringarna och stubvisning") enable interface with JavaScript ("Använd gränssnitt som inte använder JavaScript").
• Go to recent changes.

What happens?:

The top of the page show links to show or hide some types of changes, among them:

"Dölj mindre ändringar | Dölj kategorisering av sidor | ⧼wikilambda-rc-hide-wikifunctions⧽ | Visa Wikidata"

The ones for minor changes, categorizing, and Wikidata are shown correctly. The one for Wikifunctions is undefined.

What should have happened instead?:

If the recent changes page can show Wikifunctions changes and the message for Wikifunctions is actually needed, it should be properly defined and made translatable.

If it's not needed, it shouldn't be shown.
