No, it doesn’t. This does is the only thing that does:

(progn
  (set-frame-parameter nil 'undecorated nil)
  (set-frame-parameter nil 'width 100)
  (set-frame-parameter nil 'undecorated t))

Yeah, I glanced it over too and didn’t see anything. I don’t know
enough about the macOS SDK to even know how a part of the window
wouldn’t be clickable. If it weren’t for iTerm2, I’d think that they
somehow broke borderless windows entirely, but iTerm2 seems to resize
properly…
