Overview: For interactive sites designed to be used in fullscreen, a drag down gesture closes the fullscreen window. This happens frequently during casual use. 

Steps to Reproduce: 

1) Visit https://8w.8thwall.app/ios-fullscreen-bug on an iPad running iPadOS 13.3

2) Allow camera + motion access to begin AR experience and tap the nearest surface to plant trees.

3) Tap 'FULLSCREEN' button to open site in fullscreen. Continue to tap until inadvertently dragging down. 

Window exits fullscreen.

Expected Results: Fullscreen should not affect app functionality; user should continue to plant trees without disruption.

Build Date & Hardware: Tested in Safari on iPad Pro 11" running iPadOS 13.3 [latest stable release as of 1-27-2020]
