Any progress? It looks like nothing happened to fix this regression since above mail, but I'm looking at things from the outside and there it's easy to miss something, so please tell me if that's the case.

Ciao, Thorsten

Thanks for the follow-up.
A fix has been identified and a patch is prepared. We are currently running regression testing to ensure the fix does not introduce any unintended issues. We will share the patch on the mailing list once regression validation is complete.

Thanks for your patience.

Regards,
Prashanth
