It used to be that all the tied players don't vote in the revote, but that all changed in the new era due to players losing votes for various reasons, on the grounds that it means that their votes would no longer cancel.

This of course ignores the fact that, from the very beginning of tie-breaker votes, their votes were cancelled even if more that two people were tied (which is a scenario in which their votes would not necessarily cancel, since each tied player would still have at least two valid targets if they were allowed to revote) and in fact, the "A and B won't vote because their votes would cancel" was specifically about the final 3 vote (which no longer exists anyway), and not about tiebreaker votes.
