Start with the reproduction's init(), test(), reload(), and graph.zoomTo() entry points, focusing on the different center-coordinate APIs used when saving and restoring the view. Compare the saved center and zoom with the restored viewport in G6 5.x. Done means reloading restores the same center and zoom without the reported position offset.
