As you commented in the summary, you need to be able to handle scenes more cleanly.
As a quick experiment, I overwrote InspectedWin3js.getInspectedScene from the console
InspectedWin3js.getInspectedScene = function() { return XXX.testscene; }
refreshed, and it all worked fine.
It looks as if a InspectedWin3js.setInspectedScene function would be a simple and valuable addition;
any GUIs to search for scenes and give a choice could be a later addition that built on it.
Looks a very promising extension.
