Description

This happens when some of the rows are expanded and I try to scroll down. The lower boundary of the rendering list moves up together and eventually moves out of view.

The behavior can be replicated in the ui-grid tutorial page.

  1. Go to http://ui-grid.info/docs/#/tutorial/216_expandable_grid
  2. Expand all on any demo grid at the bottom of the page.
  3. Scroll down

Screen shot before expand: capture

After expand and scrolling: capture2

Notice that it ends at row 18 while expanded but it's not the last item in the list.

Research direction
Investigate the expandable grid feature in ui grid, specifically the scrolling behavior when rows are expanded. Look at the grid's rendering logic in files related to expandable rows and virtual scrolling. Check if there are any existing fixes or discussions in the repository.
