This was never an issue with the classic editor, because it was a collection of minor improvements.

By the way, the 2017 editor is a MediaWiki product (source editor), just not a single MediaWiki enabled production site I know of (except Fandom) is using it. And the skin that Fandom put on top of it, isn't helping things.
