I'm aware that questions that are edited within 5 days of being put on-hold are bumped into the Reopen Queue.
However, it's not clear whether rolling back the edits will remove it.
I'm curious about this as there's been a case where a user has made an insubstantial edit to a closed question, which has put it into the Reopen queue - I obviously can't tell whether they voted for it themselves, but there's strong evidence to believe they have (based on past patterns).
