So when I comment out the "refresh via find(stableId()) after receiving
persist()'s response EntityProxy" and simply use the response EntityProxy
as-is, the error gets thrown when I attempt to re-edit it.
It's not thrown when checkStreamsNotCrossed processes the parent
EntityProxy (called CatalogItemProxy), but one of it's children (which is
created at the same time, they have a 1-to-1 relationship with each other)
called ProductProxy (path="product"). This was unexpected to me.
Here's the wire data *without* the refresh via find(stableId())
