What does this implement/fix? Explain your changes.
This is a bug fix. The 'historic root block number not correct' challenge is not salted. This means that if the challenge commitment is front-run, the original challenger would be locked out from sending a new commitment because they could not generate a new commit hash by changing their salt.
