I have been testing this as well with a friend trying to prepare for a Standard tournament tomorrow. It appears the sideboard bug only applies to the player who creates the challenge.
So in this case both, Standard and Historic Bo3 Tournament Challenges are unplayable with one player having only 7 sideboard cards.
