Pretty sure it does. I still only use comments for that as rarely as possible, because it introduces visual clutter.
In general, I'd advise against doing that, because it kind of defeats the purpose of a deterministic formatter... I'd like to be the formatter the source of truth and not have devs argue about linebreaks. (The formatter for Dart does an extremely good job there, I'd love ktfmt to be a bit more like dartfmt, but imo it's by far the best option for kotlin btw)
So if I were you I'd probably open a feature request on GitHub (which I'd not expect to be implemented anytime soon) and use this workaround if I really really cannot bear the readability of a section of code.
