ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK) on idle stream

I have a few streams running through an envoy proxy and am seeing the same behavior mentioned in #309 .

Specifically after 5 minutes streams timeout with a POST net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK) error. I do have the max_grpc_timeout set in the envoy config file in the way mentioned in the documentation from #309.

I don't see any other known bugs around server side streaming. Are there potentially other settings or is maybe there's a gotcha of an idle timeout of 5 minutes even with the grpc timeout turned off (I'm fairly certain the streams are only dying after 5 minutes of inactivity)?
