Description of the problem

• I define allowedAnimals in aaaschema.json as an array of objects
• I generate the code. A RootModel is generated and it works.
• I define allowedAnimals as object with additionalProperties: false in bug.json
• I generate the code. The model of the first schema has been edited and now the RootModel has extra: forbid (which is not valid)
• I rename allowedAnimals in bug.json with a different name
• Now the generated code of aaaschema.json is correct again.

Goal

We don't want bug.json definitions to interfere with the generation of the models for aaaschema.json

Issue

Somehow, allowedAnimals definition in bug.json add extra: false to allowedAnimals RootModel generated for aaaschema.json which result in an:

• Incorrect behavior
• Invalid output
