Calling deselect() here will emit a selection change event for every option on the list. That's fine, but it will change the behavior of subscriptions to optionSelections. Instead of getting 1 event on selection, people will get 1 event per option (so, 50 events for a 50 option list). So I'd also add a filter to optionSelections to ensure we're only catching events from options that have selected set to true.

Also can you move this out into its own function?

Done, but instead of setting a filter on optionSelections, I've change to only call the deselect function on the option that was previously selected.

Please let me know if this PR needs any other changes
