The goal is to add a class so when assigns are not public, their descriptions can be styled similar to whispers... this is a light way to reassure admins of assign message visibility.
The previous behavior was:
1. Assign a topic to someone
2. Close the topic with the setting unassign_on_close enabled
3. Assign the topic to the same user as before
This caused small broken or empty posts to be displayed.
This commit also introduces system specs
