Accumulation table bug fix

[AinaMerch]

Motivation and Context

Loop variable state is stored by creating shallow copies of the objects. Loops that mutate a nested part of an object will not have their state displayed properly. We need to fix this by creating deep copies.

@AinaMerch good work. So in addition to updating the changelog, you should add test cases to illustrate this new behaviour.

Oh yes, and make sure to also update the documentation website to remove this limitation!

@AinaMerch good job adding test cases. You should update the documentation webpage to remove the mention of the limitation you fixed.
