📝 Description

Contracts with the exact same deployed bytecode can be verified by hardhat but cannot be verified on explorer.

Test contract verified by hardhat: https://sepolia.explorer.zksync.io/address/0x1097f8a418d36e3aB3A1B386A7977F67672Ec4Fc

Contract with the same deployed bytecode: https://sepolia.explorer.zksync.io/address/0x121f49040C4Ed3FA766557b6989B88aa3ea82082

The zksolc version, solc version, contract name and contract code are all copied from https://sepolia.explorer.zksync.io/address/0x1097f8a418d36e3aB3A1B386A7977F67672Ec4Fc , but explorer states that the deployed bytecode is not equal to generated one from given source.
