Description
While testing [MapboxGLAndroidSDKTestApp](https://github.com/mapbox/mapbox-gl-native/tree/release-boba/platform/android/MapboxGLAndroidSDKTestApp) ([`release-boba` branch](https://github.com/mapbox/mapbox-gl-native/tree/release-boba)) found 👇
This is the [`SimpleMapActivity`](https://github.com/mapbox/mapbox-gl-native/blob/release-boba/platform/android/MapboxGLAndroidSDKTestApp/src/main/java/com/mapbox/mapboxsdk/testapp/activity/maplayout/SimpleMapActivity.java) running in a Nexus 5 (Android 6.0).
Steps to reproduce:
1. Launch `SimpleMapActivity`
2. Zoom in (quick double tap with 1 finger)
3. Zoom out (quick single tap with 2 fingers)
4. As shown above map scrolls when it shouldn't
Noting that it doesn’t reproduce always.

Research direction
Start by reproducing the issue in SimpleMapActivity at platform/android/MapboxGLAndroidSDKTestApp/src/main/java/com/mapbox/mapboxsdk/testapp/activity/maplayout/SimpleMapActivity.java on the release-boba branch. Follow the zoom-in and two-finger zoom-out steps on Android, repeating them because the problem is intermittent. Done means zooming out no longer scrolls the map unexpectedly.
