Summary: This fixes [#15801](https://github.com/facebook/react-native/issues/15801) We ran into a strange crash on iOS (debug only). After removing the clutter I was able to reproduce it in a tiny app. You can check it out [here.](https://github.com/simonracz/textinput_stress) The UI in JS and native are not always in sync (which is okay). Due to this, a native view might call back into JS, which is no longer present in the shadow view hierarchy there. I think this should be also okay. TextInput in some cases calls into [setIntrinsicContentView](https://github.com/facebook/react-native/blob/6d67e2dbbcd658b7f845ebb0d0156bd64dc68226/React/Modules/RCTUIManager.m#L382), where it triggers an overly enthusiastic `NSAssert` and crashes the app. Check out [textinput_stress](https://github.com/simonracz/textinput_stress) Rotate the simulator a few times to see the crash or the lack of crash.
