KiteDemo: Landscape without collision - Out of Bounds

While testing in KiteDemo - //UE4/Release-4.16 CL 3420042 in Binary – trying to find the limits of the Caution: Out of Bounds UMG, I found a landscape static-mesh that did not have collision.

Repro Steps:

1. Have Kite Demo downloaded
2. Launch Engine Version being tested
3. Open Kite Demo project
4. File > Open Level > GDC_Landscape_01 (Map is located inside Content/Maps/GoldenPath)
5. Select Window > Levels
6. Right click inside Levels window and select Select All Levels
7. Right click inside Levels window and select Load
8. Select the dropdown next to the Play button and choose Standalone Game
9. Aim the arrow in the Mini-map towards the top right corner
10. Move forward towards the border (hold shift to increase speed and E to go upward)
11. Keep going (you will eventually hit an invisible wall, you will start flying to the left a bit)
12. Continue to fly towards the Mountain adjacent to the invisible wall

Result:
Character can go through the mountain
Expected Result:
Character is blocked by the mountain
Frequency:
4/4 - 100%
