Fullscreen Not Functioning when Windows Task Bar is Docked Vertically on the Left

If the Windows Taskbar is docked on the right side of the screen, when Playing in Editor (Standalone Mode) game AND/OR a final packaged game, entering fullscreen results in the game window opening to the right of the Taskbar, extending into the second monitor the width of the taskbar.

The licensee reports that playing in editor emulates the behavior of a final packaged game as well

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

#Position the Windows Taskbar so that it is docked vertically on the left side of the screen
#Open any project in UE4.13

1. PIE Standalone Game
2. Command Prompt: Fullscreen
   RESULT: Game window opens to the right of the Taskbar, extending into the second monitor the width of the taskbar
   EXPECTED: To enter true fullscreen mode to the point where the Taskbar is no longer visible.
