When I change the state of a drawing, it seems all the parts referenced in it change too?

I'm trying to understand which way round this tree of dependency works regarding file state.

I wasn't expecting all the referenced files to be locked into having identical state.

There must be some limit to it. For example, a frame with lots of widgets on it, surely isn't going to have to change status because there are some changes happening to the widgets mounted on it?

That isn't going to work for me if its true.

Maybe I have accidentally extended the interaction in my setup somehow.
