Part of #626 Fixes #20124 This is essentially a call back that happens when an instance withe the same key as an existing tracked instance is attached. The existing instance is always retained, but the interceptor gets the chance to change property values of the tracked instance. This will typically be used to copy over values from the duplicate instance (i.e. painting from a detached entity) or just skip the duplicate. Interceptor implementations are provided to do these two things.
