This is a testharness.js-based test.
[FAIL] WebSocket constructor with matching targetAddressSpace 'loopback' succeeds
  Failed to construct 'WebSocket': The subprotocol '[object Object]' is invalid.
[FAIL] WebSocket constructor with targetAddressSpace 'private' throws TypeError as it is an unsupported legacy alias
  assert_throws_js: function "() => {\n    new WebSocket(SCHEME_DOMAIN_PORT + '/echo',\n                  {targetAddressSpace: 'private'});\n  }" threw object "SyntaxError: Failed to construct 'WebSocket': The subprotocol '[object Object]' is invalid." ("SyntaxError") expected instance of function "function TypeError() { [native code] }" ("TypeError")
