It does render correctly.  But I think that is only because setting a
property like zlim sets the modified status on the figure and then the
window is redrawn.

I tried

set (gca, "zlim", [0 1])

and it had the same effect of redrawing the window.

This is clearly something in my system, but it is very, very repeatable so
I think it also involves Octave.
