The math behind the center handle (white square in the middle) is a little weird. This ist most obvious when I use the – and + buttons to zoom in and out. The zoom target appears to be somewhere outside of the center handle, offset to the top or bottom of the handle. This effect is more extreme the more I am in the north or south of the globe.
Expected: When I place the handle at a specific position and zoom in or out, the handle's position doesn't change.
