• NoFrameworkModule — plain HTML
• Other (please specify below)

Add new item i.e. AddRefComponent adds recursive child element to parent array.

To Reproduce
Steps to reproduce the behavior:

1. Upload the following recursive schema and layout into the playground at https://hamidihamza.com/ajsf/
2. Click Add button for the parent array
3. The nested child array (recursive) item is added to the parent
