With large data and grouping, expand/collapse rows seems to be very slow.

描述

I have more than 60000 rows and group them into several groups. When expand/collapse rows, it take at least several seconds to re-draw the grid.

Here is a plunker to show the problem: http://plnkr.co/edit/5C7B3RU0kLszzgyr7xyf?p=preview

However, in v2 with the same data set and grouping setting, it seems to be quite fast. Is there any way to improve the performance or why it becomes so slow in v3.

研究方向
Reproduce the performance issue using the provided plunker link. Investigate the grid's rendering pipeline, specifically the expand/collapse logic. Compare the DOM manipulation patterns in v3 with v2 to identify what changed. Consider profiling with browser developer tools to pinpoint bottlenecks. Explore implementing virtual scrolling or incremental rendering to handle large datasets.
