Description

**mapbox-gl-js version**: 0.43.0

### Steps to Trigger Behavior

1. On a map with `renderWorldCopies: true` using box zoom (shift click&drag) on one of the worlds to the left or right of world 0.

### Expected Behavior

The map should animate to the world the user box zoomed over (with the normal behaviour of swapping back to world 0 being transparent to the user).

### Actual Behavior

The map animates to the world 0 box.

Research direction

Start by tracing the box-zoom behavior for maps with renderWorldCopies enabled, focusing on how the selected world is determined and how the target bounds are passed to animation. Reproduce the issue by box-zooming a world left or right of world 0; done means the animation reaches the selected world without a visible jump back to world 0.
