描述

I need to optimize my app for IE11 or Edge. When dragging an item, it lags heavily (like ~2 fps). The same issue appears in the demo. It seems to affect the upper items more than the ones at the bottom of the grid. Do you have an idea why this is happening?

研究方向
Investigate the drag implementation in vue grid layout, focusing on how item movement is handled. Look at the GridItem component's event handlers and any CSS transitions that may cause heavy reflows in IE/Edge. Check if requestAnimationFrame is used or if throttling can be applied. Examine comments in the issue for any hints about the root cause.
