If the talk page doesn't exist, Minerva redirects automatically to an edit links. For instance, https://m.wikidata.org/w/index.php?title=Talk:Q21510382 redirects to https://m.wikidata.org/w/index.php?title=Talk:Q21510382&redlink=1#/editor/all.
This is a bad user experience since it hides the talkpage header. I suggest to remove this feature.
