DataTable: RowGroupMode rowspan does not work with virtual scroller #5651

Describe the bug

When creating a DataTable with rowGroupMode="rowspan" and a virtual scroller, only the first rows are grouped, after scrolling no other row is grouped.

Steps to reproduce the behavior

Simply scroll through the table and see the rows not being grouped by year, like they should because of groupRowsBy="year.

Expected behavior

If the rows have the same value passed to groupRowsBy, they should be grouped, even with virtual scroll.

Overall rowGroupMode and virtual scroller do not work together which is bad for performance and design. I have the same problem. I hope for a fast fix.
