The following code demonstrates the problem:

close all
graphics_toolkit fltk
figure (1);
ax = axes ();
figure (2);
ax2 = copyobj (ax, 2);
get (2, "currentaxes") == ax2

In any graphics toolkit the resulting figure has an empty "currentaxes"
In the case "fltk" you can see that the new axes is not automatically redrawn.
If you click inside figure 2, the axes is redrawn and afterward the
"currentaxes" is then correctly set.
Even though "qt"  automatically draws the new axes, you also have to click in
the figure to have the "currentaxes" property updated. 
In "gnuplot" I didn't see a way to update the property.
