Not sure if this regressed or I’ve uncovered a new bug but I’m definitely not changing the number of items or the order [1], just appending things like “[FIXED]” to some of the items. When I do that, the next time someone votes or changes their votes, all the previous votes on the edited item disappear.

[1] Nor doing the thing that caused problems last time where I was using asterisks as bullets but then also numbering the items so the poll got confused by the two ways of specifying list items.
