I have the exact same component in 2 different sandboxes.  The component uses `lightning:recordEditForm` and is passed an object name & Id.  There is a lookup field to the Account object that is supposed to display as an output field in the form.  I'm getting 2 different outcomes on page load..

Org A: When the component's `recordEditForm` loads, the Account loads and the __r related record also loads.  I can see this by debugging the event params onload of the form, like this

Org B: The exact same component, in the exact same context, loads the Account field, but DOES NOT load the __r related record.  So what I'm left with is a blank output on the Account field in the UI.

As you can see, the __r JSON does not load, so the form doesn't display the Account Name in the form.

I'm a sys admin in both orgs, with Modify All & CRUD access to Account object & the base object I'm working with - so it's not FLS or anything like that.  Can anyone help explain why this would load in one context but not another?
