DataTable: Subheader row group with sorting

Describe the bug

Subheader row group works wrong when you apply grouping on DataTable wihout sorting, or with sorting by different field than group field. If rows with same values go exactly one after another before applying grouping, they they will be grouped together, but if they are separated by rows with different value, they will be grouped to different groups.

I took the grouping stackblitz example from the documentation and change sortField to "status" in it. As you can see, the group by name has split into several groups.

Steps to reproduce the behavior

1. Take DataTable without sorting, or with sorting by one field;
2. Apply subheader row group to DataTable with another field;

Expected behavior

Rows are grouped with the groupRowsBy property regardless of sorting in the table

Start with the linked StackBlitz reproducer and inspect the DataTable subheader row-grouping entry point used by the example. Reproduce the split groups with no sorting or sorting by a different field, then verify that rows sharing groupRowsBy are rendered in one group regardless of the table's sort field.
