NPE when right-clicking in Horta 3D viewer

[carshadi]

Occasionally, when first loading a workspace, I get this error when right-clicking in the 3D viewer to bring up the rendering options (not on a neuron)

This is resolved by selecting an arbitrary point on a neuron, then right-clicking again away from the neuron to bring up the rendering options

This is an issue we know about, but unfortunately, we've never been able to reproduce it on command and get any traction addressing it.

Fixed for 9.14.
