BIC Response
This is not a valid bug report because the suggested check (if (signer == address(0))) is done within the ECDSA library itself. See line 154: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/cryptography/ECDSA.sol#L154.
For these reasons, we are closing the submission and no reward will be issued.
