It does that because the "bounding box" that Visual uses to determine
the autoscaling is slightly larger whenever the outer sphere is on the
far left, right, near, or far edge of the scene. We have been thinking
about an appropriate means of controlling this kind of situation, but
haven't settled down on a solution, yet.

In the meantime, you can try setting the undocumented parameter
display.minscale to something like 0.9. Feel free to experiment with
it, but I think it is a relic from some internal testing before my
time. It's behavior will change in the future (maybe even replaced)
with something more suitable for public consumption. You probably
shouldn't set it outside the range (0,1].
