Hi Danny, it's because there is kind of a technical complication with trying to persist the hidden property.

In many situations, the original object is hidden as a normal part of the command sequence.

For example with object dragging, when you are dragging the object around the object you see is a new one that has been transformed, and the original one is hidden until you finish the drag, at which point either it will be removed or if you canceled it will be shown again.

But at one point when hidden states were just directly persisted to object copies, that kind of "automatic workflow related hiding" was being persisted to the copied objects. So it's because of that problem that the hidden state is not persisted to transformed objects currently.

Probably in v3 I'll be able to fix that up, I've written myself a note to look into it.
