Why does "Copy to interactive learning" starts a new session?

Hi there!

When I review a conversation and click on “Copy to interactive learning” or when I am in interactive learning and click on “Correct action”, there is a action_session_start event between the last event of the conversation and what I will start now. Basically, only the slots are taken over.

Is that on purpose or is that a bug?

Thanks for your help! Nicolas
