Device: Google/Huawei Nexus 6P. Split touch is disabled (haven't tried it with that yet)

To reproduce:

1) go into a world
2) hold down a finger on the touchscreen while pressing the Forward button
3) while touching the screen and the Forward button, press the Home button to background Minecraft
4) go to the multitask screen and bring Minecraft back to the foreground

Expected: Minecraft goes to the pause screen, and I can tap Resume to continue playing

Actual result: Minecraft goes to the pause screen, and no touches respond. When I hit the Back button to manually dismiss the pause screen, there's still a circle on the screen where I originally touched the screen before backgrounding the app.
