Describe the bug and the steps to reproduce it

If we have a table with infinite scroll and expandable rows, without make any expand/collapse, the new rows coming from the scroll will be expanded by default, but once I collapse one row, when we make a new scroll, the new rows will be collapse by default, but should be expanded.

Steps to reproduce it

1. Load more rows with infinite scroll
2. See the new rows coming with expanded = true
3. Collapse one row
4. Load more rows with infinite scroll
5. See the new rows coming with expanded = false

ACTUAL RESULT:

1. New rows coming with expanded = false

EXPECTED RESULTS:

1. New rows coming with expanded = true
