@SentryMan, I've (hopefully) fixed the issue, added more tests, and a new benchmark case. Would you mind reviewing and applying [this patch](https://github.com/user-attachments/files/23626853/headerNormalize-v2.patch), please?

I've updated the JBS issue title as @eirbjo suggested. @SentryMan, could you also rename the PR title to match it, please?
