Not sure why the test in the CI is failing. In my local run, the test case pass.

BTW, here is (AI-agent generated) documentation of the added tests (I did check, but may have missed something) COVERAGE_REPORT.md

[guhetier]

I started a re-run for the test, it seems unrelated to this change. I'll look into it. I'll try to review the PR shortly.

@guhetier, abandoning this PR, as we pushed commits for bbr testing (which is not yet complete and require more work) to this branch. Opened a new PR #5653
