Window No Longer Captures Mouse After Closing Console

When PIE, (Standalone) after bringing up the console, typing a console command and closing console, the standalone window no longer captures mouse. Instead the user must select the game window with the mouse to re-engage the game.

Regression: This does not occur in previous versions of the Engine.

1. Open any project in UE4.11.2
2. PIE (standalone)
3. type "~" to open Console Commands
4. type any Console command and hit enter
   RESULT: The mouse cursor is free from the game to select anything on the desktop, including the game window
   EXPECTED: Game window to capture mouse inputs after entering a console command
