iOS map panning only works from the edge

[bwobbones]

On Android, I can use my finger to drag the map around from any point on the map. In iOS I can only move the map if i start the gesture from the edge of the screen.

I'm using NS7 and Vue. I can't reproduce this issue in the demo app. disableScroll is false.

Is that intentional? Or a setting? I can't find anything in these or the mapbox API issues that describes this behaviour.
