I would like to test if the issue persists with

I forgot to mention that the approach probably won't help. We still
have a generic fallback that tries non-minimized QNAME instead of
finishing with negative answer, and there are some additional cases when
minimization gets turned off. I think it covers the typical issues,
and
it's also triggered in this case, as shown in subset of my verbose log:
