Transaction generated by ckb-cli deploy gen-txs is rejected

Rejected with following information:

[send cell transaction]: 0xe61b097a77057c116116e39a884c79ecd30046b1c90dca8437f68bff8c7da247
Send transaction error: jsonrpc error: `Server error: PoolRejectedTransactionByMinFeeRate: The min fee rate is 1000 shannons/KW, so the transaction fee should be 1591 shannons at least, but only got 1506

There is not enough fee after balancing:

ckb-cli/src/subcommands/deploy/tx_builder.rs

Line 137 in c9d814d

let balanced_tx = balance_tx_capacity(

Increasing fee-rate to 1200 can solve this issue.

It happens in multisig scenario. The delta is computed as 1591 - 1506, resulting in 85. Interestingly, this value aligns precisely with the combined size of a pubkey hash (20) and a signature (65). I am contemplating whether there could be an error in the witness calculation for multisig. See:

Please find the attached info.json used in deployment with the transaction.

The expected fee-rate is 1600 but actually it is lower than that.

I simulated twice multisig contract(omnilock) deployments, one new deploy and one upgraded deploy, and both were successful at the default fee-rate of 1000.
