Description

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?

Contributor guide

Research direction
Profile the drag event in IE11/Edge to identify rendering bottlenecks. Check if the issue is caused by re rendering of all items on each drag move. Consider using requestAnimationFrame or throttling.
