emacs -Q

M-x set-variable RET pop-up-frames RET t
M-x tool-bar-mode ; turn it off, to start from zero
M-x pp-eval-expression RET (frame-parameters)

In frame *Pp Eval Output* search for `tool-bar-lines' => 0 (good).

In original frame (do all of the commands here, except isearch):

M-x tool-bar-mode ; turn it on
M-x pp-eval-expression RET (frame-parameters)

In frame *Pp Eval Output* search for `tool-bar-lines' => 2 (wrong).

In original frame (do all of the commands here, except isearch):

M-x pp-eval-expression RET (set-frame-parameter nil 'tool-bar-lines 1)
M-x pp-eval-expression RET (frame-parameters)

In frame *Pp Eval Output* search for `tool-bar-lines' => 2 (wrong).

In original frame (do all of the commands here, except isearch):

M-x pp-eval-expression RET (set-frame-parameter nil 'tool-bar-lines 3)
M-x pp-eval-expression RET (frame-parameters)

In frame *Pp Eval Output* search for `tool-bar-lines' => 2 (wrong).

etc.  It seems that the `tool-bar-lines' is always either 0 or 2.
