Task & Schedule Tree Collapses when Hierarchy is Modified

The top half of the Task & Schedule window displays a tree of tasks. When you open the window, the nodes in that tree are expanded/collapsed just as you left them when you last opened the schedule. This is a convenient feature for usability.

However, if the Task & Schedule window is open when changes are made to the dashboard hierarchy (for example, by saving changes in the Hierarchy Editor), the task tree will collapse completely, losing the user's working context.
