Expandable grid child presentation is refreshed when scrolled out and back into view
When you have an expandable grid open, scroll the parent grid so that the open expanded grid disappears from the screen. Then scroll it back into view. Notice that the expanded grid presents as if it had initially been drawn. Notably, inline edits are not rolled back so it does not appear to be refreshing the data, just the appearance. The Tutorials have examples of this behavior in section 216 Expandable grid: On any of the tutorial examples, sort the grid, scroll the parent so the expanded grid is out of view and then scroll back. Notice the sort of the expanded grid is reset. In the third tutorial example of retrieving data scroll the expanded grid to the bottom. Then scroll the parent grid. Notice the expanded grid is scrolled back to top. I don't believe this is just a sort or visible row problem. I discovered it because my expanded grid had a tabset and the selected tab reset. I believe this to be an issue because this behavior could be a unwelcome UI experience for a user.
This is still an existing issue 5 years later - any ideas? I'm trying to manually do a redraw to get around this.
