That zone's pretty messed up. ns1 and ns2.twcable.com always return
REFUSED for 136.142.in-addr.arpa/NS, but they return a delegation for
234.136.142.in-addr.arpa to cdp-wn-tm-5-01.inf.twcable.com, which doesn't
exist. So named ends up treating it as a lame delegation.  I would suggest
contacting Charter Communications about this, they need to fix the zone.

"qname-minimization relaxed" really ought to be able to work around this,
though, and I thank you for bringing it up. You can file a bug report at
gitlab.isc.org/isc-projects/bind9/issues if you wish.
