Research direction
The bug involves footer column aggregation disappearing when the column is scrolled out of view. Investigate the ui grid footer directive and its update logic. Look at how the grid handles column visibility during scroll events. Determine if the issue is reproducible in the latest version. Consider adding unit tests for aggregation in scrolled columns.
