Bug with dependent fixed-length array within another

[samath117]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

When there is a fixed-length array ("type": "array" with items field an array) inside a dependency inside another fixed-length array, the inner fixed-length array is not rendered (or is rendered as if has zero length). This is a minimal failing example -- without the outer fixed-length array, the dependency, or either of the fixed-length arrays being variable-length, it renders correctly.

The following playground links illustrate these cases:

• Failing Example
• Working Variation w/o Outer Fixed-Length Array
• Working Variation w/o Dependency
• Working Variation w/ Variable-Length Outer Array
• Working Variation w/ Variable-Length Inner Array

Expected Behavior

Like the working variations, the failing example should render the inner array element.

Steps To Reproduce

See the playground links shared above for the precise schema needed.

Thanks for the report and thorough examples and reproduction @samath117 . At first glance it seems like the issue is that default values for fixed arrays inside of "dependencies" or "then" are not being populated, so the form fields never render. If you manually fill in form data, the properties eventually appear.
