Chat delete user : No mention and Green dot

What I was trying to do:

See my chats

What I expected to happen:

A user that deleted his account to be identified as such and the green dot not been present

What actually happened:

I see a

1. deleted user with his username

2. avatar with SM inside

3. a green dot.

This may need more grooming but it is definitely not the expected behavior. For posts, typically, we add deleted user for both username, names & photos (with a x inside).
