Hi Krzysztof, sorry for this oversight. I did a rebase work for this 
series and found I couldn't fetch 'Reviewed-by' tags for the rebased 
one. I think that issue has the same substance with what you point out. 
Thank you for providing me the clues and apologize again.

Would it be acceptable for me to submit a v2 revision that only updates 
the 'change-id' in the cover letter? This approach seems to resolve the 
issue on my side and should help reduce your workload as well.

Best Regards,
Hangxiang
