No. There was a piece of trivia (https://miraculousladybug.wikia.com/index.php?title=Catalyst_%28Heroes%27_Day_-_Part_1%29&diff=336586&oldid=336577) on this page that stated THIS episode was the first episode to do so. OP was clearly asking about when Ladybug defeated Vanisher in this episode, why didn't that count.
