I have two issues with multiple subtasks, both are rendered oddly in the list view, and they aren't rendered the same way.

The first one has 3 subtasks, and I can't find any way to get the parent issue to have the + on it so that I can collapse them in the list view.

The second one has 11 subtasks. Upon first entering the list view, the parent issue always has the + on it. However, many (but not all) of the sub-tasks are exploded out.Once I expand and collapse it, everything appears fine.
