Controller input changes for network players based on which window has focus

When testing networked multiplayer with two controllers, if the server window (editor) has focus, controller 1 controls the server character and controller 2 controls the client character. If the client window is given focus, controller 1 now controls the client character and controller 2 controls the server character.

1. Plug 2 XBox controllers into the computer
2. Open UE4 Editor (third person template)
3. In Play drop-down, set Number of Players to 2
4. PIE
5. Use controllers to move characters

Result:
Controller 1 will always control the window that currently has focus and controller 2 will control the other character

Expected:
Controller 1 provides input to player1/server and controller 2 provides input to player2/client regardless of which window has focus.
