can not show correct data when we use virtual scroll quickly down or up

We set tree grid enableVirtualization to true, and set datasource with remote data which adaptor is webapiadaptor. The remote data is a JSON file with more than 50K records.

When we scroll from top to bottom, and bottom to top, and repeat..., every time things are different.

As shown in picture, now we scroll to top, but ID shows 1381, not 1. Similar issues happened during scrolling - again and again.


We have noticed that it was caused by the inconsistent response sequence of HTTP requests. The response of the request sent first is longer than that of the request sent later.
