This is a followup to emacs-devel thread with 100% reproducible test case.

On master with any earlier revision before the tabs branch was merged,
and compiled for a Motif or Lucid toolkit, i.e. any build without external
tool-bar, i.e. not GTK builds, (also note that some confusion on emacs-devel
with inconsistent results was caused by not using the required `make clean'
in the lwlib directory after switching toolkits) running

emacs -Q -f tool-bar-mode

that disables tool-bar-mode before it's displayed for the first time,
and evaluating

(let ((initial (assq 'outer-size (frame-geometry))))
  (tool-bar-mode 1)
  (tool-bar-mode 0)
  (list (assq 'outer-size (frame-geometry)) initial))

=> ((outer-size 680 . 693) (outer-size 680 . 676))

indicates growing of the frame's height.

Evaluating the same again produces the correct result:

=> ((outer-size 680 . 693) (outer-size 680 . 693))

OTOH, in a new session again with emacs -Q -f tool-bar-mode

(progn
  (tool-bar-mode 1)
  (assq 'outer-size (frame-geometry)))

=> (outer-size 680 . 693)

(progn
  (tool-bar-mode 0)
  (assq 'outer-size (frame-geometry)))

=> (outer-size 680 . 693)

It's strange that the results are the same because visually
the frame's height grows.  Maybe this is specific to the window manager?
My window manager is MATE.
