Because how the proxies work is they add an additional root key into the 
(victim) browser during some form of configuration.   DANE makes the injected 
root key no longer valid.

Of course, certificate pinning and other techniques has the same problem, and 
IMO, killing the idea of TLS proxies is a feature, so DANE's general 
incompatibility with TLS proxies is a feature, not a bug.
