3831187 - ALV: Selected row lost after leaving REUSE ALV Fullscreen

An application uses REUSE_ALV_GRID_DISPLAY to present data. The following behaviors are observed:

1. Row selection not reflected after BACK:
The user selects one or more rows in the ALV grid and navigates back using the Back function. The application is expected to mark the selected rows in the internal data table by setting the value 'X' in the designated checkbox field. However, upon return, the selected rows are not marked, the checkbox field remains empty.

2. Row marking not reflected on the front end after double-click:
When the user double-clicks a cell, a callback is triggered. Inside the callback, the application marks the corresponding row in the internal data table and sets the refresh flag to signal that the display should be updated. However, the change is not reflected in the ALV output, the front end does not show the row as selected or marked.
