In order to remove a FIXME, code which checks a BEGINS_WITH relation between base64-encoded strings is computed in a way which does not involve decoding the whole string. In case of padding, the remainders are still decoded, but their size is bounded by 3, which means they will be eligible for the small string optimization.
