Comment:

 == Combined Bug Reproduction and Patch Test Report
 === Description
 🟠 This report validates that the issue can be reproduced but the patch is
 not working as expected

 Patch tested: https://github.com/WordPress/wordpress-
 develop/pull/8789.diff

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.28
 - Server: nginx/1.29.0
 - Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 - Browser: Chrome 138.0.0.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-Five 1.2
 - Plugins:
   * Test Reports 1.2.0

 === Reproduction Steps
 1. Use the code provided by OP
 2. 🐞 There is an unexpected array transformation

 === Expected Results
 - JSON empty values are kept as-is

 === Actual Results with Patch
 1. ❌ Values are still being stored as arrays

 === Additional Notes
 - I've been reading over the report, but I still have some elements
 unclear. I have not thoroughly read the proposed code in PR 8789, so I
 wonder if the code is simply not finished yet or if I'm missing something.

 - Also @jorbin your PR is an incremental code over PR 8789?
