bug#46827: Broken initial size of GTK3 frame

One clue I found is this: With a "good" run, update_frame_tool_bar gets
called three times with an existing FRAME_GTK_WIDGET, with a "bad" run
it gets called four times before the initial frame appears.  The two
traces below are for Emacs 27 where the first, "good" one is without the
zero_vector assignment and the second, "bad" one is with it.
