Client Characters that slide past the Server Character while on top of a Movable Actor can become de-synchronized from their Server counterpart

Client Characters that slide past the Server Character while on top of a Movable Actor can become de-synchronized from their Server counterpart. Does not occur on top of Static Actors.

Hard to explain, but I've included a sample project and a video for reproduction. Run the Client character straight into the Server character and eventually the character will slide around the Server character on the Client but not the Server.

Reproduced in 4.8.3 binary, 4.9.0 binary, and Main (CL 2684415)

Info from latest test. I used the client and ran into the back of the sever character. If done right you will notice the client character seems to pop through the server character and run off the edge

1. Open the attached project
2. Run the Client character into the Server character, attempting to stay touching the Server character while moving in its direction

Result:
Eventually, the Client's character will slide around the Server's character on the Client, but not on the Server. The Client's character on the Client and the Server will be de-synchronized in position.
