I'm back with another large avatar issue. 
When this style property is set:
[XB] Message and Elements --> Layouts --> Message Layout 3 (Modern)
It results in the postbit looking disjointed. Specifically there is overlap on the postbit itself, and the left triangle arrow is on top of the message body. The online user indicator is also no longer on the avatar.
I love the flexibility in the message layout options, definitely leaning towards that one if that can be addressed for larger avatars. Currently using Message Layout 0 (disabled).
