EthereumJS returning wrong public key

I’m using https://iancoleman.io/bip39/#english to generate a random 12 word mneumonic with the following settings.

• Mneumonic language: English
• Coin: Ethereum
• Derivation Path: BIP44

It generated the following mneumonic movie diesel same toe bachelor acquire roast ghost siege thought possible scale

The first address – public key – private key is the following
Address: 0x67D8641084F8088D5996E39Bae07F9Dc4130307F
Public Key: 0x030c8931742732ca2e0956ecf385acc886a54428ad84eb884aa2c72f1008a2c858
Private Key: 0x78f7e532bf8d7c79d8ef42c75a361f53a8db8c38e4cb1828788ef119c48f6896
I wrote this to generate the same public key from the private key.

var Wallet = require('ethereumjs-wallet')
var EthUtil = require('ethereumjs-util')

// Get a wallet instance from a private key
const privateKeyBuffer = EthUtil.toBuffer(
  '0x78f7e532bf8d7c79d8ef42c75a361f53a8db8c38e4cb1828788ef119c48f6896'
)
const wallet = Wallet.fromPrivateKey(privateKeyBuffer)

// Get a public key
const publicKey = wallet.getPublicKeyString()
console.log(publicKey)

the log statment prints 0x0c8931742732ca2e0956ecf385acc886a54428ad84eb884aa2c72f1008a2c8582bc50fd34eb9e111ae2969205d7af28e9b5050be4ae6ca43df74fc65b9af5803

This is not the same public key for the corresponding private key, why is this?
