Clicking received bubble (MSConversation), does not invoke iMessage extension app.

When a MSConversation message bubble is recieved (previously sent from the iMessage Extension app), clicking on the bubble has no effect. However, if you click in the Messenger entry (textfield?), then re-click on bubble, the extension app gets called.

Is this a bug, or is there something I should have done inside the extension app, to prevent this from occuring?

Currently I do the following on a button tap:

<...snip...>

// Add the message to the conversation.

conversation.insert(message) { error in

if let error = error {

print(error)

}

}

dismiss()

<...snip...>

Thanks for any guidance.
