I made this https://ru.wikipedia.org/w/index.php?title=%D0%A8%D0%B0%D0%B1%D0%BB%D0%BE%D0%BD:%D0%9A%D0%BD%D0%B8%D0%B3%D0%B0:%D0%9B%D1%83%D1%80%D1%8C%D0%B5-%D0%90%D0%B4%D0%BC%D0%B8%D1%80%D0%B0%D0%BB%D1%8B-1941-1945/doc&diff=108478188&oldid=93717675 edit, clicked save and was shown the conflict interface. (perhaps the mouse could quickly click twice on the save button) But the interface compared my edit with the revision (the last in the history of the template) from 2018!
