ChimeraX shows starting model not aligned to output model for exosome.cif

[tomgoddard]

In the multistate exosome example one of the starting models (Ski7_3izq...) is only used in state 3, but it is being displayed unaligned on the output model for state 2. It should be hidden if it is not part of the shown output model.

More detials: The ChimeraX log says it failed to align Ski7_3izq_modeller_vmd.pdb chain X starting model to the sphere models in exosome.cif. The reason for that is that the exosome example has 2 states, Rrp6 and Ski7 and the unaligned starting model is only part of the Ski7 state. But ChimeraX is only trying to align it to the Rrp6 state output models. The reason for that is that ChimeraX shows just the first output model group. There are 4 groups in the exosome case, the first 2 or two clusters of Rrp6 and the second 2 are two clusters of Ski7. So ChimeraX is initially showing only the Rrp6 output model for cluster 1. But it tries to align all starting models to that output model, and it can't align the Ski7_3izq... starting model since it is not part of that state. The sensible behavior would be to hide that starting model.
