Hi, I noticed my MR was closed in favor of MR!8846, which contains nearly identical changes submitted just 6 days ago. Could you help me understand why my MR waited 3 months without review while a similar one was processed so quickly? I'd like to learn if there was anything I missed in my submission process.

The main difference is the tests. When adding a change that checks certain flags, it's important to also test other possible flag combinations to demonstrate that you are checking the right flags.
