Client Animation is not updated on Server with "Replicate Movement" disabled

Client Animation is not updated on Server with "Replicate Movement" disabled

See Additional Info URL because the user appears to have done some debugging on this.

1. Create a project using the ThirdPerson feature pack
2. Remove the player pawn in the map and add a player start
3. Change the game mode to ThirdPersonGameMode
4. Set number of players in the multiplayer options to 2 (under play)
5. Go to ThirdPerson_AnimBP and add a print right after the update animation call (see img below)
6. Run the project and you should see 4 prints: two server side, two client side
7. Go to ThirdPersonCharacter blueprint and untick Replicate Movement
8. Run the project again

Result: There are 3 prints: one server side, two client side. You'll also notice that the client character animation is not updating in the server viewport
Expected: I'm unsure if "Replicate Movement" is supposed to control whether the AnimInstance is frozen.
