getAccount on two difference indices clobbers their UTXOS

Consider getAccount() on two separate accounts to keep UTXO management isolated:

        client.account0 = await client.wallet.getAccount({ index: 0 })
        console.log('client.account0 :>> ', client.account0.BIP44PATH)

        client.account5 = await client.wallet.getAccount({ index: 5 })
        console.log('client.account5 :>> ', client.account5.BIP44PATH)

        const accountInfo = await client.account0.getUTXOS()
        const accountInfo5 = await client.account5.getUTXOS()

        console.log('account0 UTXOS', JSON.stringify(accountInfo[0]))
        console.log('account5 UTXOS', JSON.stringify(accountInfo5[0]))

produces:

client.account0 :>>  m/44'/1'/0'
client.account5 :>>  m/44'/1'/5'

account0 UTXOS {"address":"yPKSLNqX7ygjw2Btts2dRjwQBHWDB1sBiN","txid":"5a2731453e2f1f9cc99ceb13123166e2b7694965b35206886d7c4e338d7fca3c","vout":1,"scriptPubKey":"76a91420e7f2b5e320abb31fca0fa65e20f0efc8ac056d88ac","amount":123.01180996}

account5 UTXOS {"address":"yPKSLNqX7ygjw2Btts2dRjwQBHWDB1sBiN","txid":"5a2731453e2f1f9cc99ceb13123166e2b7694965b35206886d7c4e338d7fca3c","vout":1,"scriptPubKey":"76a91420e7f2b5e320abb31fca0fa65e20f0efc8ac056d88ac","amount":123.01180996}

account5.getUTXOS() shows the UTXOS from account0 (and the other way around), they get clobbered together.

Expected Behavior

I expected them to be isolated for greater coin selection control.
