Turned out that MetaMask sometimes returns the data inside originalError. As mentioned here: #4454 (comment)

So, this issue would be about implementing the same as #5962 but for version 4.x

And here is the place where the modifications are needed:

web3.js/packages/web3-eth-abi/src/decode_contract_error_data.ts

Line 41 in 137542a

errorArgs = decodeParameters([...errorAbi.inputs], error.data.substring(10));
