--
When SSL decryption is on and an eligible connection is seen, SSL dissector
takes over the TCP port replacing the regular protocol dissector for that port.
Consequently, the unencrypted part of conversation is seen as 'Ignored Unknown
Record's.

The expected SSL dissector's behaviour is not to push out any regular
dissectors but be instantiated by them 'at the right time' (e.g. after a
STARTTLS command).
