mapbox' project function depends on the center of the map being east or west of antimeridian

Nobody has claimed this yet.

map.project provides different results depending on the center of the map.

How to reproduce:
a)
- center map on the east side of the Pacific, e.g. 160°W,0. Zoom=3. north up.
- call map.project( [-160,0])
=> you might get something like [857,488] (almost the center of a large window)

b)
-now move map center to west side of anti-meridian, e.g. 160°E.
- call map.project( [-160,0]) again
=> you get something like [-2806,483]

But WHY -2806? The spot of -160,0 is still visible. The screen projection should yield something like [1200,480] – a jump right of a) because the map has been moved to the rigth as well between scenario a) and scenario b).

Am I missing anything?

**mapbox-gl-js version**: v1.12.0
**browser**: any

Start with the map.project API and reproduce the two cases at zoom 3 with map centers near 160°W and 160°E, using the coordinates and expected screen positions in the issue. Trace the antimeridian handling in the projection path; done means the visible point produces a consistent nearby screen coordinate after the map center crosses the antimeridian.
