Rotate the view via command won't save state

Thank you @hainm for this lovely widget :-) I was wondering if there is any way to make changes to the viewer controls permanent / encoded into the JavaScript state. For example in the picture below, if I rotate the view v1 by r1, it alters the earlier view but the state does not persist into cell In [72], or into the state when the widget state is embedded into the notebook.

We are looking into this because we've found the nglview widget to be an amazing tool for nbsphinx tutorials, which can get rendered into HTML pages with interactive molecule viewers. It would be fantastic to get the full functionality that is available in a normal notebook.

Embedded state:

There is a work around (#948 (comment)) but we still need to fix this bug (we did fix it before).
