Details:

(Singling out this one from bug #44307)

Zooming in/out of (rotated) 3D plots works only on the XY plane. As a
consequence the picture gets distorted in the Z-direction.

Matlab zooms in/out on the plane on which the rotated 3D-plot is projected, as
I would expect.

It can easily be seen doing:

plot3 ([0 1], [2 3], [4 5]);

rotate the plot a little,

and zoom in/out.
