I have been looking into this (and the related 14056) now. With a more
simple scenario using
(defun my-set-frame-size (&optional frame)
(tool-bar-mode -1)
(set-frame-width frame 30)
(set-frame-height frame 10))
(add-hook 'after-make-frame-functions 'my-set-frame-size)
(server-start)
in the server Emacs, I can reproduce the bug for a 24.2.92.1 native
Windows build I happen to have around here. For that build, the client
frame indeed does not support the requested height but uses the default
initial height instead. I cannot reproduce the bug for any later build
I have here including one of 24.5.50.1. So I suppose that the bug has
been fixed somewhere in between these two builds and mark this bug as
done.
Very belated thanks for the report, martin
