πŸ› Bug Report for anvil-zksync

πŸ“ Description

Replaying the following tx:

anvil-zksync -d replay_tx --fork-url sepolia-testnet 0x46c0db5b243cec2ef4016143a7f17718815420f0e863197b432f4231a1b2c57c 

We see the following details:

17:08:40  INFO βœ…  [SUCCESS] Hash: 0x46c0db5b243cec2ef4016143a7f17718815420f0e863197b432f4231a1b2c57c
17:08:40  INFO Initiator: 0xe85b66fca403bc35bcae17ce7758e942aea65dc0

17:08:40  INFO Refunded: 0.0000033807 ETH

The refund specified is Refunded: 0.0000033807 ETH whereas if we review the tx on the block explorer it is reported as Refunded: 0.0000044942 ETH

As a result the calculation for fees is also different.
