All scenes and several entities "became unavailable" while editing a scene

[123 (Taras)]

WTH is there no way to create or edit scenes without realtime state changes?

It isn’t at all intuitive that editing a scene will immediately apply it. This is often incredibly inconvenient, and sometimes potentially dangerous. I might want to edit a scene involving a door lock, or a valve or switch that controls an important appliance, or any number of things where actually applying it would be undesirable. It seems like the default should be to be able to edit and make changes without those being applied in real life, with a “Preview Scene” option to use if desired.
