Description

Prerequisites

What theme are you using?

mui

Version

5.13.2

Current Behavior

I have hit a strange bug, not sure where to look, so I will post working and not working schemas. Hopefully, the maintainers will have an idea of what is wrong.

#1. if-then with contains. The conditionally rendered schema has string keys. This works. #2. if-then with contains. The conditionally rendered schema has integer keys. This does not work.

Both work well when liveOmmit and omitExtraData are set to false

Expected Behavior

I would expect that both scenarios work with turned on liveOmmit and omitExtraData. However it seems that they reset the field that is used for rendering the dependent schema, but only if that field options match the keys in the dependent schema. This looks like a bug to me

Steps To Reproduce

#1

Research direction
Investigate the behavior of `if then` with `contains` in the form when `liveOmmit` and `omitExtraData` are true. Compare the working case (string keys) vs non working case (integer keys). Look into the library's handling of `allOf` and `if then` in combination with array `contains` conditions. The relevant code likely resides in the `@rjsf/core` or `@rjsf/utils` packages, particularly the logic for resolving conditionally rendered schemas and omitting extra data.
