`linked` field doesn't print with `--verbose`

When I test signature with create-account, --verbose doesn't print linked field in operations but it is used to making hash.

$ sebak wallet payment ${PUBKEY} 10000000000 ${SECRET} --create --verbose
{
  "T": "transaction",
  "H": {
    "version": "",
    "created": "2018-10-02T10:57:45.403746651+09:00",
    "signature": "4ty1Pv7Phc3CEeGLCP8mjZfEC259VR1MBgyVHzQXTcWjuSiwxVQ2AQKxy2HjGTCDrmdE29z8ZNZ6GxuDyEay2p9M"
  },
  "B": {
    "source": "GDIRF4UWPACXPPI4GW7CMTACTCNDIKJEHZK44RITZB4TD3YUM6CCVNGJ",
    "fee": "10000",
    "sequenceid": 0,
    "operations": [
      {
        "H": {
          "type": "create-account"
        },
        "B": {
          "target": "GDTEPFWEITKFHSUO44NQABY2XHRBBH2UBVGJ2ZJPDREIOL2F6RAEBJE4",
          "amount": "10000000000"
        }
      }
    ]
  }
}

Start at the sebak wallet payment ... --create --verbose entry point and trace how the create-account operation is serialized for verbose output and hashing. Compare the displayed operation with the fields included in the signature payload; done means the linked field used for hashing is also present in verbose output.
