Sort Column Gets Reset (Server-Side Data)

The sort column direction is getting reset after new data is retrieved from the server and set in the table. It also gets reset on page changes, rows per page changes, and search text changes. Is this intended behavior, and is there any way to override it?

## Expected Behavior
The sort column should not change when new data is retrieved and set from the server.

## Current Behavior
The sort column direction is getting reset after new data is retrieved from the server and set in the table. It also gets reset on page changes, rows per page changes, and search text changes.

Start by reproducing the server-side table flow and trace how sort state is handled when data, page, rows-per-page, or search text changes. Done means the selected sort column and direction remain unchanged after each of those updates, with the behavior verified against the reported case.
