The MainMenu widget isn't loaded when the player returns to the MainMenu map from the InGame menu in Multiplayer Shootout. This happens in PIE and in a packaged project.
Reproduced in 4.8.0 and Main (//depot/UE4/Promotable-CL-2588320). This is a regression: did not occur in 4.7.6
1. Open the 4.8.0 version of Multiplayer Shootout
2. Open the MainMenu map
4. Click Play
5. Hit Q to open the InGame menu
6. Click Leave Game
The Main Menu widget does not appear when the Main Menu map is loaded
