It seems most likely that when giving a gift of a glass dish with candy on it, the giver would have to toivel it first. Although when giving a plain dish, we would follow the shittah that it’s considered a “kli sechorah” rather than a “kli seudah”, in this case, by putting the candy on the dish, the giver is using it for food. As one poster noted above, there is no heter to use a vessel once; that is most likely an error which cropped up because some confused it with disposable untensils.
Simply lining the dish with paper would not help; to avoid the tevilah requirement, it would need to be placed in something which could hold the candy on its own.
