1. Start Emacs -Q

2. Eval this progn form in *scratch* with C-x C-e at the end of the
   form:

      (progn
        (setq ns-use-native-fullscreen nil)
        (tool-bar-mode -1)
        (set-frame-parameter nil 'fullscreen 'fullheight)
        (dotimes (_ 6)
          (toggle-frame-fullscreen)
          (sit-for 1)))

Expected behavior: Top line of the *scratch* buffer is visible

Observed behavior: Top line of the *scratch* buffer is cut off and
hidden under the window title bar

Other information:

I think tool-bar-mode can be left on if you wish, but repeated
invocations of toggle-frame-fullscreen seem to toggle between
demonstrating this bug and then fixing it.

6 for the number of times you have to toggle full screen was arrived at
empirically.  You may need more or less.

If you (setq header-line-format "foo") this might be even easier to
observe.

I believe I've fixed this on the master branch now. If you're still
seeing the problem, please reply to this email and I'll reopen the bug
