[whatwg] WebSocket restriction on the server's subprotocol

The WebSocket spec restricts the value of the subprotocol that the client  
is allowed to send to the server (see step 3 in the WebSocket()  
constructor algorithm). However there's no restriction on the server side  
(see step 2 of Sending the server's opening handshake). The client could  
not have asked for any subprotocol, but the server can still respond with  
a subprotocol, and the connection will be accepted.

Shouldn't the server have the same restriction as the client?
