180-182: Consistent implementation for column synchronization - Great job!

The modification of the key prop for columns (key={column-${index}-${question.columns.length}}) mirrors the change made for rows. This consistency is excellent for maintaining code clarity and ensuring that both rows and columns stay in sync with the preview.

To further improve code reusability and maintainability, consider extracting the key generation logic into a separate function. This would reduce duplication and make future updates easier. Here's a suggested refactor:

const generateMatrixItemKey = (type: 'row' | 'column', index: number, length: number) => 
  `${type}-${index}-${length}`;

// Usage:
key={generateMatrixItemKey('row', index, question.rows.length)}
key={generateMatrixItemKey('column', index, question.columns.length)}

This refactoring would make the code more DRY (Don't Repeat Yourself) and easier to maintain in the future.

Missing Tests for MatrixQuestionForm Component

The MatrixQuestionForm component currently lacks dedicated unit tests. To ensure the robustness of the implemented synchronization fix, please add tests covering:

• Adding rows and columns
• Deleting rows and columns from various positions (top, middle, bottom)
• Verifying that the preview updates correctly after each operation

Line range hint 1-224: Summary: Effective fix for matrix survey sync issue with room for additional testing

The changes implemented in this file effectively address the synchronization issue between the matrix question editor and its preview, as described in issue #3281. The solution focuses on updating the key props for both row and column QuestionFormInput components, ensuring proper re-rendering when items are added or removed.

Key points:

1. The fix is targeted and minimal, reducing the risk of introducing new issues.
2. The implementation is consistent for both rows and columns, which is good for code maintainability.
3. The solution aligns well with React best practices for key management in lists.

To ensure the robustness of this fix, consider adding or expanding unit tests to cover various scenarios:

These tests should cover:

1. Adding rows and columns
2. Deleting rows and columns from various positions (top, middle, bottom)
3. Verifying that the preview updates correctly after each operation

If you need assistance in writing these tests or would like me to propose a test suite, please let me know.
