Not sure if i fully understand everything you're doing here but i have another way in mind how we could solve this.

Instead of setting things to undefined if we select the already voted one, and then handle this in the handleVoteClick, we could just update the check in isVotingDisabled with a function areAllSelectedAnswersAlreadyActive where we compare the 2 arrays
