Hi team, any update here? We had to ultimately ship our own fix to retain the original behavior merchants expect, which entailed complicating our business logic using a combination of numVariants and hasOtherVariants (which is a property that may not exist depending on the type of selection payload).

If the bug could be fixed, that would be appreciated. Thanks.
