I have the fix for the issue, once the issue is accepted, I will open pull request for the same. Currently I am not able to raise the pull request as it is dependent of fix for #3152

This fix needs to be done along with or after Pull Request #3153. To test the fix, issue 3152 needs to be resolved.

Hi @artembilan,

The issue mentioned in PR is a new bug that is introduced in 5.1.7 and above and is related to Original_ Header handling.

This issue is related to Sequence Handling that has one unhandled scenario. If we agree that this fix can be merged along with PR #3153. I will push this fix to PR #3153

No, let's hold of from complicating that PR.
I'm about for final review and merging that one.

We can come back to this afterwards.

So, stay tuned!
