描述

When I use representative() to make an element draggable by just its child, the window jumps underneath the cursor such that the window’s top-left corner is under the cursor.

Demo: http://jsfiddle.net/eveLzaaw/2/ representative bug

研究方向
The issue demonstrates a bug where the window jumps to the cursor when starting a drag using representative(). Investigate the drag event handling in jquerypp, particularly the representative() method and how it sets the drag origin. The provided jsfiddle and gif show the undesired behavior. Look at the source code for drag events (likely in /event/drag/) to understand how the initial position is calculated and why it might be offset incorrectly.
