Select all entities (including Hatch) in attached test drawing.
If you try drag Line (see attached "demo__drag_line.png") with left Mouse button then Anchor (or Reference?) point will be nearest point on Line.
But if you drag Hatch (see attached "demo__drag_hatch.png") then Anchor point wil be point (0,0). This is especially annoying when dragging Hatch with Border - you must be lucky to hit Line of Border.
I think in this situation Anchor point must be Point of Hatch border which is closest to mouse cursor hit point.
