Description

What changed?

Previously, formio.js conditionals were failing with error / not working in scenarios when conditions were applied to array data structure components (Edit Grid, Data Grid, etc.). This PR fixes this behavior.

Why have you chosen this solution?

Tried different solutions, but since this logic never really worked fine, ended up writing a recursive function that would generate array of components paths with indexes, which are later iterated one by one to perform conditional checks.

Dependencies

None

How has this PR been tested?

I added automated tests to cover both tickets cases, also performed a good batch of manual tests through portal
