They do show up, not the connections themselves, but the initiation, no?? At least I always see lots of 101 Switching Protocols responses on sites that use websocket, it might be some sort of nonstandard gateway though. Never used it so dunno.
Of course even if that's the case, you gotta load the website with the network inspector already open, to see the initiation.
