bug#32207: 26.1; can't set window position with emacs 26.3

emacs -Q -g 40x20+400+400

> It is possible that 18 * 84 which gives 1512 pixels + 400

The created frame is well within my 1920x1080 screen

I used
  emacs -Q --eval "(setq initial-frame-alist '((width . 40) (height . 20) (left . 400) (top . 400)))"
to match the above.

With Emacs 25 it ends up in the correct position, but sizes
are messed up. The initial scratch window occupies some top
left portion of the window, with matching size menubars and
scrollbars in the middle of the window :-) and rest of frame
blank.

Emacs 26 works perfectly! even with off-screen positions.

I'll added this to my .xclients script (though -g ought to
work) and will check next time I need to restart X.

PS: Adding "(user-position . t)" to the -F argument of calls
to emacsclient to place frames in my other three screens,
seems to also put them where I want them too.
