Details:

If you try to immediately access the position property of a newly created
uimenu, it sometimes returns 0. The correct value is returned if a pause
statement is added between the creation of the uimenu and the get('position')
query.

To reproduce the issue, create a script containing:

++
F = figure;
t0 = uimenu( F,'Label','Menu');
%pause(0.1)
pos = get(t0,'Position')
--

Executing the script from the Octave prompt often returns 0. If you uncomment
the pause statement, the position will be 1.

(note that, as pointed out in bug #44672, the already existing menus of a
figure (File, Edit, Help) are not 'visible' as the position of the newly
created menu item should be 4 and not 1.
