The right sidebar in Impress has a section "Position and Size". When selecting an image or rectangle and moving it partly out of the bounds of a slide, the "Horizontal" and "Vertical" fields display still 0.0 as position of that object, as if the object's origin would at the upper left corner of the slide.
This is inconsistent, since an object can (not) have different positions with same horizontal/vertical offset.
