Actor Component Replication Not Working on Dynamically Spawned Components in Blueprint

Actor components that are spawned dynamically through Blueprint are not being properly replicated to the client. 

Found in 4.20 CL# 4233996 and reproduced in 4.21 Main CL# 4258917

Unable to test in 4.19, as adding a component set to replicate to an actor that is also set to replicate disconnects the client in that version. 

Original Fix caused: [Link Removed], [Link Removed], the original fix was reverted and this issue was reopened

1. Open the attached project
2. PIE with 2 Players

Result: The actor component's event is not called on the Client

Expected: The actor component's event is called on the Client, the same way that it is called on the Server.
