Repro steps:
1. Create a new project
2. Add an Input Field and check the "Hide mobile input" setting
3. Build and Run on an Android device
4. Press the Input field to open the keyboard
5. Try to close the keyboard by touching the area just above it where the input field preview would appear if "hide mobile input" wouldn't be used

Actual: That area is nonresponsive and doesn't close the keyboard
Expected: The keyboard closes when touching any part of the screen that doesn't belong to the keyboard
