How to view multiple reactions

Now that apple has introduced reactions to iMessage, I was wondering how you could view multiple reactions on a message. If you use the reaction feature in a group chat, you can see every reaction sent by people in the group chat. However if you're texting one individual through iMessage and they reacted more than once to one message you can only see the most recent reaction. If I click on it, it only gives me the option to react to my own message, not view every reaction that person made. Does anyone know how to see all reactions?
