                name: Record4
                fields:
                  - name: child4
                    type: CommonChildRecord

the preview reports what is presented in Screenshot1

As you can see r2 is of type Record2 which equal (structure-wise) to Record1 (used by r1). However, the report for r2 is "Adheres to: Any or null" while the report for r1 is: "Adheres to Object or null".

This inconsistent reporting seems to be related with having a nested field (in this case of type CommonChildRecord) marked as nullable. But the issue for some reason does not affect the first record.

Now if I make the nested field not nullable, there is no issue, even if the parent is nullable. (rendering of cases of r3 and r4 reports: "Adheres to Object or null")

The above issue also affects the payload in the examples section: see below:

Expected behavior

For r2 the adheres to should be Object containing a a field of type String

Screenshots

Screenshot1:

How to Reproduce

1. Visit https://studio.asyncapi.com/
2. Paste the above payload
3. See in the preview that r2/child2 is presented with "Adheres to Any" while r1/child1 is shown correctly.
