As you can reproduce your issue reliably, please bisect the changes
between 6.12.101 and 6.12.105 to identify the breaking commit. That
given we can have a look if it is a known regression already or needs
to be reported upstream yet.

Let me know if you need instructions for the bisecting steps!

Regards,
Salvatore
