This is totally expected. For an image layer, OpenLayers simply requests an image with a bounding box that matches the map viewport. That bounding box can exceed the world bounds (i.e. go beyond -180° or +180°), and GeoServer will handle that just fine. Client-side wrapping is only needed for tile and vector layers.
