For some languages, Special:NewLexeme requires entering the lemma language separately. Until a few weeks ago, it was possible to pass lemma-language as a URL parameter to Special:NewLexeme to prefill the form fields. Now the lemma-language parameter is ignored and the lexeme can't be added unless the user manually fills in that field. Other parameters still work.
Examples:
- https://test.wikidata.org/wiki/Special:NewLexeme?lexeme-language=Q377&lemma-language=en&lexicalcategory=Q1979&lemma=test
- https://www.wikidata.org/wiki/Special:NewLexeme?lexeme-language=Q669623&lemma-language=mis&lexicalcategory=Q1084&lemma=test
It would be useful for this to work again, because then people can create links/bookmarks for common combinations.
