Closes #4573
The issue here was that
util.getCoordinatesCenter
, in addition to finding the center of the given coordinates on the x-y plane, also attempts to choose the largest zoom level where one tile would cover the area spanned by the given points. Since latitudes outside of [-85.05113, 85.05113] don't fit even on z0, we would get a negative zoom value, which later violated assertions inTileCoord()
