BIND 9.11 no longer respects edns-udp-size?

This machine has 'edns-udp-size: 1432' and, indeed, in the reply, it displays this buffer size. But it does not respect that limit. Here, with a big DNSKEY RRset, BIND should have truncated the answer and set the TC bit but it didn't: % dig @194.0.9.1 DNSKEY ma ; <<>> DiG 9.10.3-P4-Debian <<>>
