Unfortunately, that doesn't help as it removes axis lines. It looks like I
can't use segments3d() without knowing what the bounds are of the current
axes and I don't know what to call to expose those.

Thanks again for your help, though, I appreciate it. Hopefully this gets
fixed in a future release!
