There is code to check whether the element to attach to is missing. If so, the position is currently set to 0, so it appears in the center. However, if the element later is present (due to a changing DOM), the original position is not recovered. A related issue is that the arrow is updated properly (assuming the current position is correct), but an arrow is never removed. So if a DOM element later is removed, the guider will show in the center, but the arrow will still be present.
