         Fix an issue where the drag surface was preventing hover events for sharing blocks.
         This does not prevent user interaction on the blocks themselves.
-        This was previously pointer-events: none, but that allowed clicks to fall through
-        causing incorrect stack clicks on duplicate, and prevented the correct
-        cursor from showing when dragging over the toolbox to delete.
